Part 14. Answered by: P. T. Kekkonen
British Bulldog revolver
A friend asked me to identify a pistol that he found in his grandfathers stuff. I believe
it to be a 11 mm revolver made in Belgium called the British Bulldog. It is a small pocket
revolver with a gate opening for loading and a bar that goes into the center of the
cylinder is pulled out and rotated to extract empty shells. Any info on this gun would be
great.
Thanks, Todd
There are 16 pages full of Bulldog revolver drawings on
the book "ASE-ATLAS" by ALEXANDR
B. ZHUK. On some pages of this book are drawn as many as seventeen somewhat different
models of "American", "British" and "Belgian Bulldogs". It
is impossible mission to identify some individual revolver without seeing it.
In
Belgium was at least a hundred little anonyme gun manufactures producing cheap pocket
revolvers and shotguns. It is impossible to identify exactly the British Bulldog revolver,
if the name of manufacturer is not engraved or stamped on it. Usually it was not. The
"British Bulldog" was not a trade-mark of a revolver, but a pattern or a family
of pocket-sized revolvers, made by (mostly) anonyme Belgian firearms plants, usually
located in Liege/Herstal region.
Some Bulldogs were made also in France and original models actually in Britain. Bulldog
handguns are more or less faithful copies of WEBLEY "Metropolitan Police"
or "Royal Irish Constabulary" revolvers, but calibers of them varied
from 5 mm to 11 mm (if not up to .476 Eley or .577 Boxer) European, British or American
cartridges. Those same Belgian firms produced also "American Bulldog" revolvers,
chambered for the short revolver cartridges popular in USA. There were, of course,
produced the "Belgian Bulldogs" too.
PS. Book "ASE-ATLAS" is available in Finland from ASE-LEHTI/ KIRJAMYYNTI. Text
is in Finnish but alphabetic order is along with Russian alphabet. Drawings are
magnificent! E-mail address of the distributor is: kirjamyynti@aselehti.fi .

Gun & ammo
Hello PT and thank you for your answers and tips on 30-06 subsonic loading. This time I
have some questiones concernig a gun and some ammunition that my late grandfather left
behind. I have attached some pictures, but will give a description of the stuff as well.
The rifle is said to be a SAKO, and the caliber is 9,3 x 53R. What can you tell me about
this gun and approximately how old it is? It has a very strange looking, but slick
fuctioning bolt. The ammunition is decribed as follow (from left to right on the picture).
1) 8.15 mm bullet diameter, soft point, head stamp P162 IVe1 4 40, green ring around
primer 2) 8.15 mm bullet, FMJ, head stamp: hlb St 1 43, red ring around primer 3) 8.15 mm
bullet, FMJ, head stamp: cg St+ 12 41, red ring around primer 4) 8.15 mm bullet, FMJ
w/black tip, head stamp: p249 IXg1 13 40, red ring around primer 5) 8,18 mm bullet,
tapered cartridge, head stamp : R.W.S 72 x 8.18 I would very much like to have some
answers as to what this ammo is and if they are some kind of specials.
Sincerely, Lars (PV), Norway
Without a
picture of your 9.3 x 53R rifle it is impossible to say anything about origin of your
"sporterized" military rifle, intended for moose hunting. (I presume - without
more exact knowledge - that the rifle is an old "war horse"). Re-boring and
re-rifling (or re-barreling) might be done by SAKO Oy, but there were many small
gunsmithing shops in Finland, which made the sporterizing of service rifles. Actions of
them were most usually Russian Mosin & Nagant Mod. 1891 or -91/30, but Japanese
Arisaka Model 1897 and especially Model 1905 rifle/carbine actions were not uncommon.
(Rifles and carbines M/-05 were bought by Germany for White Finns before and during
Finnish Independence War/Civil War in 1918. Old models were donated by Russian Bolsheviks
to Red Finns. They were presumably captures of Russo-Japanese War 1904 - 05 from
Manchurian battlefields). Many other actions were also sporterized, like Winchester Model
1895s (captured from Russians during the 1918 War), Swedish Mauser model 1896 and even the
Austrian Mannlicher Model 1895 rifles with a straight-pull bolt action. Sporterizing of
old service rifles is still continuing: Many Winchester Mod. 1895 rifles are re-barreled
to shoot .45-70 Government cartridges; usually handloads since factory-loaded cartridges
"have not enough bullet's energy for moose hunting" accordig to our Game Act
(copied from Swedish Game Act).
Since 1962 until 1993 hunting of moose, whitetail deer and bear was banned with handloaded
cartridges in Finland, but when this insane ban was criticized by periodical hunting
magazines since late 1970s (in my writings, of course!), this ban was finally revoked in
1993, along with many other bans and restrictions, which were consequences of unlimited
dictator-like authority of the game-legislator TAUNO V. MAKKI (who was a bosom friend of
contemporary president URHO K. KEKKONEN) - and the corruption.
But back to the sporterizing: Especially Japanese rifles had too thin barrel for shooting
with 9.3 x 53R cartridges, designed by SAKO Oy sometimes after the Finnish Third
Independence Struggle (in 1941 - 44). PLEASE NOTE: These cartridges are still in
production by Sako, but with just one rather miserable old-fashioned softpoint bullet
type; not with 9.3 mm BARNES X or NOSLER PARTITION bullets. The most productive
sporterizing workshop, ASEPAJA AARRE VIITANEN in Kauhajoki, modified almost 9000 Arisaka
rifles and sold them with a stamped trade-mark: "JAPPI". Gunsmith A. Viitanen
bought a bore drilling & reaming machinery about 50 years ago, and was so able to
drill the barrels from the steel bar-stock. Now he could make the moose rifles too; no
more just 7 x 54 mm small game rifles by re-boring and rifling.
(Since 1933 until 1962 moose hunting was banned with a rifle, caliber 8 mm or less. All
kind of hunting was banned with 7.62 x 53R caliber military rifles; at least these rifles
in possession of Army personnel and members of Finnish Civil Guard, the Suojeluskunta.
That's why the Finns use caliber designation 8.2 x 57 mm from 7.9 x 57 JS Mauser
cartridges and 8.2 x 53R from the "factory wildcat", based on the necked-up 7.62
x 53R case. Caliber designation is actual or approximate diameter of a bullet, not a bore
diameter. 8.2 mm softpoint BULLET was legal for moose hunting. Designation .308 means also
bullet diameter, while .30 or .300 is a nominal bore size).
Among the privately-owned gunsmithing shops was also TAMPEREEN ASEPAJA, which made
sporterizings but designed also the actions of .22 rimfire rifles or centerfire target
& hunting rifles. Best known design of TAP was, however, the famous JATI-MATIC
submachine gun. First prototype of it was shootable in 1980. Activity of TAP was
suppressed by "hoplophobic" (or actually "MISOHOPLIC") Finnish
authorities. AARRE VIITANEN closed his shop in the late 1983, when Finland was associated
to the f..king bureaucratic organization known as C.I.P. which prevented production of
truly accurate rifles for sales by their norms and standards.
1980s was a disastrous decade to Finnish firearms industry; not only to the small custom
gunsmithing shops: Famous TIKKAKOSKI Oy was merged in SAKO Oy and forced to end firearms
production. State-owned VALMET TOURULA WORKS also merged in Sako and it's firearms
production was gradually suppressed to the end. Original name of Tourula Works was VALTION
KIVÄÄRITEHDAS; STATE'S RIFLE FACTORY, but the misohoplic State of Finland was determined
to get rid of the small arms production.
"MISOHOPLIA": What is it?
A mental disorder. Derives from ancient Greek words "MISOS":
"hatred" (for something or somebody). "HOPLOS/HOPLIS":
"weapon(s)". "..IA": "disorder/ sickness". Formerly used
term: "HOPLOPHOBIA" (coined by JEFF COOPER, as far as I know) is somewhat
incorrect diagnosis, meaning just "fear of weapons". Misohoplics HATE weapons
and the persons willing to possess the firearms or other weapons. Highest degree of
misohoplia was the (U.N.- supported!) plan to collect privately-owned firearms and
destruct them by burning at the stakes. It was no more a symptom of any "phobia"
but a sign of much more serious madness.
(My friends! Please, tell this to Jeff Cooper: "Doc" P.T.Kekkonen is
diagnosed the pestilent sickness of our enemy. He know also the correct medicine: A soft
metal with specific gravity 11.34 grams per cubic centimeter. Chemical symbol: "Pb".
Parenteral application. Dosage: "Quantum Satis" - usually in capsules).
About the cartridges: Most of them are 7.9 x 57 mm JS
(Mauser) military ammo. Last one is designed for hunting guns with "break
loading". Many of them were shotgun-rifle combination guns or drillings.
1) 7,9 mm TM-bulleted cartridge. Issued to German troops for hunting only; not for
warfare. Producer: Presswerk GmbH, Metgethen, East-Prussia. Loaded in April 1940. (TM
means Teilmantel; "partially jacketed" with a soft point of naked lead or with a
soft copper "ballistic tip").
2) Usual ball cartridge. Producer: Metallwarenfabrik Treuenbrietzen GmbH, Selterhof,
Germany. Steel case with (usually) single slightly enlargened flash hole, although it has
a Berdan primer. Loaded in January 1943.
3) Usual ball cartridge. Producer: Finower Industrie GmbH, Finow, Germany. Reinforced
steel case. Loaded in December 1941. Finower cartridges were very accurate. Issued usually
for the snipers and for target practice of sniper aspirants.
4) Tracer bullet gartridge for snipers; "practice tracer". Producer: Finower
Industrie GmbH, Finow, Germany. Loaded in 1940.
5) Civilian cartridge 8 x 72R SAUER. Derivation of century-old 9.3 x 74R FOERSTER
cartridge (which is still well-known and popular especially in Central-Europe, where
hunting is a hobby of wealthy aristocracy only). The cartridge is not necked-down like
usual "wildcats" but it's case is tapered from rim to mouth. Producer:
Rheinisch-Westwälische Sprengstoff, Nurenberg or Troisdorf, Germany. Loading date
unknown. (It was mandatory to stamp it on the heads of military cartridges only).
Production of 8 x 72R Sauer is ended several decades ago. Cartridge was designed about in
1910. It became never as popular as the "big brother" 9.3 x 74R, which is still
going strong.

Sound trap idea
I would like a conformation of your mailing address in order to send you some
"support". I also have made a suppression device of my own. I am waiting for
some time to do testing would you please offer some comments. I made it for a single shot
bolt action .22 using subsonic ammunition. I will send you sketch but in case you can't
open it I will offer a brief description:
At a distance of 85mm from the crown starts a row of 5 ports (under the barrel) measuring
3mm with a spacing of 8mm on center. The row of ports is encased in a 50 mm copper sleeve
that runs 90 deg to the rifle bore. It's sleeve's upper end is capped off flush with the
top of the barrel and the lower end tapers down to 3/4" female pipe thread (the
distance from the top of the barrel to the pipe thread is 110mm) the pipe thread now
couples to the middle of a 260 mm X 60mm "Resonance" chamber filled loosely with
soft cellular foam. The resonance chamber runs parallel to rifle bore center line.
Question is: What material should be in the chamber, should I port the chamber, should I
baffle any or all of it, would it suppress better if it blew off into a larger chamber?
This isn't designed to be concealed in any way so size isn't critical. I relies this isn't
"Normal" but I wanted to try to build a different mouse trap. Any thoughts or
referrals would be greatly appreciated.
Mike, in Canada
The only
way to support our activity outside Finland is to send cash (paper money) to our postal
box. Address is:
GOW, P.O. BOX 525, FIN-80161 JOENSUU, FINLAND, EUROPE.
Canadian dollars are also welcome; not USDs only. Annual fee is 20:00 (twenty) CAN$.
Majority of our non-Finnish visitors are forgotten the support fee, a.k.a. "The Debt
of Honour"! Our economic situation is again very "frustrating".
I can imagine your suppressor concept by the written description and found it be
excessively large and complicated. Swiss designer THURLER patented about similar device in
1911 for military rifles, shooting full-power loads. It was a muzzle-can, however. Heat
absorbing material were metal chips, presumably of aluminium. The suppressor for .22
rimfire rifle, shooting subsonic ammo, needs definitely no cellular foam material in
chamber surrounding the barrel. The "muzzle can" part of a suppressor is
essential! Gas exhaust ports through the barrel wall are unable to eliminate the muzzle
blast of even the .22 LR subsonic cartridge. Length of the suppressor jacket ahead of
barrel muzzle may be as short as 3 inches (75 mm) if there is a gas expansion chamber
around muzzle end of the barrel.
(See construction of BR-Tuote Reflex suppressor). The
gas bleed apertures or ports through barrel wall are beneficial, if they are drilled (AND
REAMED!) just ahead of the cartridge chamber. Two ports with diameter 4 mm, located at the
breech end of barrel (less than 50 mm ahead of the point of a chambered bullet's point)
are enough for deduction of the bore pressure and bullet velocity so that any & all
"standard velocity" cartridges shall become TRULY subsonic cartridges. The
powder gas, bleeding through these ports, should be trapped into the gas expansion chamber
around the breech-end of a barrel. Don't fill this chamber with any material lessening
it's volume! Now you need just a little, thin muzzle-can (like PARKER-HALE MM1) mounted on
the rifle. It is "horribly silent"; more noisy when the hammer or striker is
dropped on the breech-bolt than when the cartridge is discharged (unless your rifle is
autoloading).

"Perversed" bullets and the Haque
dictates
I noticed with some interest the use of reversed projectiles in military weapons. It was
known for persons to pull and reverse military 7.62 mm NATO ammo projectiles in Vietnam -
but not for silencing/suppression purposes. (Moi? Mais non!)
It was only ever done for the first round loaded in the chamber as it didn't feed reliably
from a magazine but caused massive knockdown power, similar to using a softpoint or
hollowpoint projectile. Of course you're probably "technically" not breaking the
Geneva Convention because you're still using a standard Full Metal Jacketed Spitzer
projectile... As for accuracy, at combat ranges accuracy changes are immaterial. I
wouldn't do it too often on a fine sniping weapon though, as the hot gasses will ablate
the bore.
Sherro (Australia).
Comments. This
trick has been well-known since 1899, presumably in all the battle-fields of the world -
especially since adoptment of the Spitzer bullets on military rifle cartridges. (In
Germany: 1904, in USA: 1906, in Russia: 1908, in Britain: 1914...et cetera). The Spitzer
bullet is a pointed projectile with a plain or usually somewhat concave base. (Russian
bullet "L-pulya" had a rather deep conical base cavity, like a Minié
bullet. So had also the Finnish 7.62 mm "S-luoti").
The Dum-Dum bullet "a METAL jacketed projectile with the lead core exposed on it's
POINT, or the jacket weakened with slashes/incisions" was banned by the First Haque
Peace Convention in summer 1899; NOT by Geneva Conventions! (This is an usual delusion
even on the scientific articles; not only on the pulp-novels). The "Dum-Dum
prohibition" REALLY does not ban use of the reversed Full Metal Jacketed bullets for
any kind of warfare! Also, it doesn't ban use of lead projectiles (without any jacket, or
with a paper or plastic jacket).
1st Haque Peace Convention banned also aerial bombings "from the balloons", but
because the serviceable dirigibles ("Zeppelins") and aeroplanes were not yet
invented in 1899, all the belligerents carried out aerial bombings against military
objectives and even the civilian targets - already during the First World War.
"Pumagi pumaga, a praktika yest praktika" said a Russian Red Tsar, JOSIF V.
STALIN: "Papers are paper, but the practice is practice!". The participators in
Haque Convention were mostly members of contemporary very most arrogant European
"cream of the cream" aristocracy: Diplomatists who were BORN to become
diplomatists! Just the German delegation had some military experts among it. Aristocrats,
of course!
Delegation of USA had also an expert of wound ballistics: Captain WILLIAM CROZIER (1855 -
1942). He lectured - hour after hour - about the tricks "how to evade a Dum-Dum
prohibition". Diplomatists yawned (most of them didn't simply understand the
ballistic terminology) - or felt sick if they were able to comprehend even the essentials
of the lecture. No suggestions of Capt. Crozier were accepted to the communiqué of Haque
Convention. Delegation of USA went home before the end of Convention. I cannot understand,
why the US warriors didn't use softpointed or hollow-point rifle bullets, even in the
Korean War fifty years ago or in the Viet-Nam conflict! They were never bound to the
dictates of Haque Conventions 1899 and 1907, and opponents of them were Communists: Not
human beings at all!
On our GOW/Finnish (SUOMEKSI) site is an article "HAAG 1899"
about the tricks carried out during a full century, to evade the "Dum-Dum
prohibition". I am very sorry, but I have not enough time to re-write this long
article also in English! (And my motivation for writing in English is once again fading
away: Too many visitors are forgotten their "Debt of Honour"; our nominal annual
fee! Is it too arduous to draw a bill/banknote from a cash automat, get an envelope &
stamp, and type or write with long-hand our P.O. Box address?!). Drawings and other
illustration of "Haag" story may be, however, interesting.
Use of real EXPLOSIVE bullets was banned already in 1867 - 68 by the Declaration of St.
Petersburg, with many interesting exceptions: Use of explosive or incendiary projectiles
with the weight less than 400 grams is BANNED just against the non-covered personnel
(wearing an uniform) or their "beasts of burden" in the ground warfare between
REGULAR ARMIES of civilized states. Use of these projectiles is ALLOWED in civil wars,
counter-insurrection operations or fighting against the insurgent natives in the colonies,
and against criminals/ culprits. It is also ALLOWED to use explosive bullets against
COVERED enemy personnel or beasts of burden, as well as against buildings, trains, all
kinds of motorized vehicles, balloons, dirigibles, aeroplanes, ships and steam-boats or
motor-boats.
It is a well-known fact that Soviet-Russia violated St. Petersburg's Declaration during
the wars in 1939 - 45 more frequently than other nations of the world did altogether!
Example given: ADOLPH HITLER allowed issue of cartridges with explosive/incendiary 7.9 mm
"B-Geschossen" to the German infantry NOT until February 1945, just a couple of
months before fall of the True Germany. Issue of these cartridges was allowed just to the
snipers, for use in the Eastern Front only..!

Replica scope for a Parker-Hale Whitworth replica
rifle
Thank you for your response. Do you know of the scope manufacture that made the Repro
scope and mount for the Parker-Hale rebirth Whitworth for the Gibbs Company?
Billy
Sorry, I
don't know exactly! LYMAN PRODUCTS Corporation made in 1977 - 78 the 33.75 inches long
scopes with 4 x magnification and a fixed cross-wire reticle for their Centennial Rifle.
(Just a batch of 1000 rifles were made by STURM, RUGER & Co. I don't know, how many
scopes were produced by Lyman). Also I don't know, whether these scopes were mounted on
the PARKER-HALE/ GIBBS Co. Whitworth replica rifles. Mounts for them were presumably made
by Parker-Hale. You should try to contact them yourself and ask. (I am unable to consult
any producer of guns, ammo or equipment, due to my lack of direct contact with Internet or
e-mail).
I have also a very faint recollection that a Japanese manufacture of optics, TASCO, has
produced sometimes the replica scope sights, with brass tubes and fixed cross-hair
reticles for reproduction rifles. Shorter variation of these Tasco brass-tube sight is
about authentic for the Whitworth repro, if mounted on the left side (NOT on the top) of a
rifle. As far as I know, there were long top-mounted and shorter side-mounted scope sights
for Confederate States of America's Whitworth sniping rifles; some of them were imports
from Europe, some others captured from Yankees. Majority of CSA snipers shot, however, by
use of the open iron sights or tang-mounted high peep sights on their Whitworth rifles.

Needs a full-auto Stechkin APS!
1) I discovered your site, and I would obtain some info concerning our common passion.
Here in Belgium we have the government collectors agreement to buy all
"historical" weapons. I have now a Finnish "Luger" and the holster
marked: J T R. Could you help? I suppose it would be: Jääkäri Tampere Rykmentti,
right?
2) Another important request: Could I buy in your country, with my agreement, a "Stetshkin
sarja-automaattpistooli" in his original configuration? Not like in Germany,
single shots! Any address would be upmost appreciated.
daniel
1) Wrong!
Abbreviation "T R" means "Tykistö Rykmentti" (Field
Artillery Regiment). There was a "Jääkäri Tykistö Rykmentti" in
Finland until 1924.
2) There are not many firearms importers in Finland able to import and export Soviet/
Russian special firearms, like full-automatic Stechkin APS,
in our knowledge. (A vast majority of Finnish firearms importers avoids any connections
with GOW). The most probable source of APS in Finland is Mr. P. J.Virtanen. His
e-mail home page address is http://personal.inet.fi/yritys/pj-waffen-guns
.
Connect also with ASETALO Oy. This company is nowadays a sole importer of some
Russian Tula (Tulskiy) firearms in Finland.

Finnish 47 mm rifle grenades and mortar bombs
I am searching for any information about Finnish rifle grenades used during the Winter
War. What I know to date is this: * A rifle grenade launcher adapter did exist, was
possible of a spigot-type, and was possibly designated AL-36 * The grenade fired
was the Model 32 Egg Grenade, possibly with a fin attachment * Finnish Army TOE of the
period confirms that such grenade launchers existed... at least on paper!
That's it! That is all I have been able to find. I would like to know the following: *
Year of introduction * Numbers produced * Manufacturers * Design specifications * Use in
the Winter War? Can you help?
P.S. By the way, you wouldn't happen to know anything about a light mortar tested by the
Finnish Army and National Guard some time in the mid-30s? Possible designation was Model
35, and as far as I know it was never accepted for service. It also fired the Model 32 Egg
Grenade, which indeed appears to have been derived from a 47 mm mortar bomb!
Blake
Finns
didn't use rifle grenades in remarkable quantities during Winter War, since the deep snow
annihilated effect of tiny 47 mm grenades. Actually, effect of even the 81 mm mortar bombs
was questionable, because point-detonating fuzes of them were'nt sensitive enough.
Manufacturing licence of fuzes was bought from France, i.e. from a "warm
country", where use of Stokes-Brand mortars in the ambient temperature MINUS
40 degrees Celsius (also -40 degr. F) was "non-probable" if not
"impossible". Why just French fuzes? It is still a dark mystery! There are
persevering hearsays about bribery, but nothing is possible to prove today, 65 or 66 years
later.
In mid-1930s tested especially Finnish SUOJELUSKUNTA (Civil Guard a.k.a. National
Guard) the rifle grenades and grenade launching adapters model VIVIEN-BESSIÉR,
plus very awkward-looking rifle carriages. Vivien-Bessiér device was a tube, mounted on
the rifle muzzle like a suppressor. Original V-B grenade had a central longitudinal bullet
passage. It was launched with bulleted cartridge. Bullet "triggered" the
time-fuze with fixed 5 seconds delay before explosion of a grenade. V-B grenades were
efficient for trench-warfare during the First World War, because they air-bursted above
enemy trenches - if they were launched with a correct elevation to the KNOWN range (and if
the time fuze fuctioned correctly, which was not always quaranteed during hasty war-time
production).
Soviet-Russian designer M.G. DYAKONOV "improved" the idea of Vivien-Bessiér in
1932 with a Stalinistic principle: "Lushshye vsjeh dlya Svataya Voyna!"
("All the best for a Holy War" - for the Worldwide Socialistic Revolution). In
theory, the Dyakonov's rifle grenade was ingenious: Bayonet-mounted tube on the rifle
model 1891/30 was rifled. (Adapter tube of V-P design was smooth, unable to gyro-stabilize
the grenade in it's flight). Rifle Grenade D-32 had the projecting lugs fitting into
rather steep and deep rifling grooves of the launcher tube.
Grenade D-32 had a londitudinal bullet passage like a tubular bullet, lined with a steel
tube, in it's center axis. Inside diameter of the passage was similar to the diameter of
Russian/Soviet rifle bullet "L pulya obr. 1908 goda", backed with 3.2
grams of powder. Every ballistician presumably knows that the kinetic energy of a rifle
bullet is mere 1/3 (slightly more or less) from the "calorimetric" energy of a
powder charge, while the usually wasted "muzzle blast energy" may be 45 to 50
per cent from the chemically bound, a.k.a. calorimetric energy of the powder charge. In
theory there is much more energy available for launching of the rifle grenade than for
propelling of bullet, but the rather short grenade launching tube is not a "2nd class
Perpetuum Mobile". Like in all machines, there is a minor gain and major loss of
energy. Considerably less than 30 % from the energy of a muzzle blast might be gained as a
kinetic energy of the rifle grenade.
Therefore designer Dyakonov added a booster charge into the base end of his MINIÉ-bullet
shaped grenade. It was placed into the skirt of grenade when needed. To the short ranges
were grenades launched without a booster, which was needed for long-range shooting.
Grenade filling was tri-nitro-xylene in chrystalline form. Shell was of cast iron, usually
tin plated and pre-fragmented with the grooves like a British "MILL's Bomb", but
the grooves are less deep and more narrow. The time fuze was ingenious (but just in
theory). It was adjustable like fuze of an artillery shrapnel shell but located on the
rear end of grenade. Graduation of rotating adjustment ring was from ½ second to 12
seconds with 1/4 second steps. (This mentioning is from my memory. Forgive possible slips,
please!). Timing was very precise, because the blackpowder "vein" was circular;
not like the powder filling of BICKFORD's cord.
Along with a grenade launching tube were issued a special sight with elevation scale
(clamped on the left side of Soviet 1891/30 rifle) and a bipod. Shooting from a
shoulder-supported rifle might be about a suicide because of the recoil, especially when
the grenade was equipped with a booster charge (almost as heavy as the charge of a 7.62 mm
Mosin-Nagant cartridge with "L-pulya obr. 1908 goda"; bullet weight
9.65 grams, charge weight 3.2 grams of nitrocellulose rifle powder).
According to official directives the rifle butt was leaned on the rear edge of a pit, dug
on the soil and supported with a board if the soil was soft. D-32 grenade was designeded
to air-burst 2 to 6 meters above the trench of an enemy, but the theory in a designer's
office is just "a grey theory" and the practice on the war theatres is a crude
PRACTICE.
There were very precise tables of elevations and timings of the fuzes issued for the users
of D-32 rifle grenades, with and without the booster propellant charges, but without a
modern pocket calculator it was simply impossible to adjust the correct flight time of a
grenade and elevation of a launcher in the battlefield conditions. The grenade was simply
a "too much too early" innovation; expensive to produce and almost useless in
hands of average privates. Finns captured the grenades D-32 and the launcher kits (tubes,
sights, bipods and timing/elevation "tablichas") during the Winter War, but they
found very soon that "the Revolutionary Innovation of a Soviet Genius" was
useless for the actual battle.
These rifle grenades were - as far as I know - only type of the r-grenades tried to use by
Finnish troopers during the Winter War. The Soviet Designer of Merit, M.G. Dyakonov,
designed also an all-steel hand grenade with a handle, type RGD-33. It is said that
Dyakonov-designed hand grenades killed or wounded more Red Army conscripts on the exercise
fields than enemies during the Soviet Great Patriotic War (1941 - 45), including the
unsuccessful attempt to march through Finland into northern Swedish iron-ore mining areas,
and finally to Norwegian fiords in 1939 -40. (This pitiful campaign, "an Infamous
War" according to the modern Russian historicians, is known as the Russo-Finnish
Winter War. Occurrences of it are well-known, but the final aspire of J.V. STALIN is
exposed since 1941 by no other media but GOW).
A Soviet hand grenade model 1933, design of M.G. DYAKONOV.
Sectional drawing, and a drawing of grenade with the detachable fragmenting sleeve fixed.
Without this sleeve the grenade was an "offensive grenade" with a reduced
fragmentation effect.
Preparations for use of RGD-33. Note that the
primer/detonator/delay column was istalled just before the fight. Later Soviet hand
grenades F-1 and RG-42 were ready for use after removal of the safety pin and release of a
safety lever. (Drawings from user's instruction table of RGD-33. Date unknown).
The Finnish 47 mm rifle grenades and the smoothbored launhcing tubes of them were rejected
soon after Suojeluskunta's trials in 1935 - 36. They were designed in England in 1932. The
fuze of them was a simplicity itself, designed for hand grenades. When the steel safety
pin was removed, just a "shearing wire" of copper, diameter about one
millimeter, kept the striker away from a flash cap, igniting a 5.5 seconds delay charge of
compressed blackpowder, which in turn exploded a detonating primer and the booster charge
of high explosive, like compressed TNT for the sure detonating of less sensitive cast TNT
main charge. The Finnish "egg hand grenades" were activated by a blow with the
fist on a broad rear end of the striker, when the steel safety cotter-pin was pulled away.
Idea of this extremely simple activation of a hand grenade was derived from French "Citrón
Foug" grenades, designed during the early phase of First World War. Those
lemon-shaped hand grenades were somewhat risky to carry. They had no safety pin, but just
a steel cap on the striker end, sealed with a paraffine wax. If the "lemon"
grenade was dropped from waist-height on the hard surface, the striker might ignite it's
time fuze. The accidents led to the idea that a time fuze of a rifle grenade could be
activated by the rapid acceleration of a grenade, when it was launched from an adapter,
mounted on the rifle muzzle.
Finnish rifle grenades were at first egg-shaped with the steel base plates on their rear
ends and somewhat modified fuzes on the point end. They had eight seconds delay from the
launhcing to the explosion. Unlike the Vivien-Bessiér grenades or Soviet D-32s, they had
not a bullet passage. It was necessary to shoot them with non-bulleted propelling
cartridges. The Suojeluskunta-designed rifle carriage was big and high - not suitable for
use in the real warfare. Probably it was built for test-shootings only, before
interruption of fruitless trials. This was presumably the "AL-35 Grenade
Launcher", you mentioned. The famous Finnish firearms designer AIMO JOHANNES
LAHTI had no connection with this unsuccessful project. He was designer of the Army
firearms. Suojeluskunta had their own constructors like NIILO TALVENHEIMO
(ammunition), CARL PELO and HARRY MANSNER (firearms). The
"biological father" of rifle grenade concept is unknown to me.
Egg-shaped grenades were also unstable in flight. The flight-time was variable and
trajectories of grenades were accordingly variable. Sometimes they exploded in too high
altitude to be effective. Sometimes they were sunk into the soil or snow before explosion
and the 47 mm shell (designed to be primarily a HAND grenade) is truly inefficient when
exploded in the soil or snow. The rifle grenade project became abandoned at least three
years before the Winter War. Presumably no Finnish rifle grenades were "shot in
anger" during this war. Soviet-Russians abandoned also their D-32 rifle grenades and
launcher adapters & other equipments soon after the Russo-Finnish Winter War. Germans
captured during the 1941 - 44 war presumably no more Dyakonov launchers and grenades than
Finns during our "105 Glorious Days" between 30th November 1939 and 13th March
1940.
A miniature mortar, shooting 47 mm hand grenades equipped with 8 seconds time fuze was
really designed in Finland, probably by TAMPELLA Oy, a famous producer of mortars
and artillery pieces. (TAMPELLA had a plant known as "SOLTAM" in Israel, when
export licences of military firearms were hard to get in Finland during the "Hippie
Era", due to the noisy protests of "peace movement", which was never grown
strong but it was very noisy, supported by Soviet communists and international "new
leftist" movement, born in USA during and after the Viet-Nam conflict).
This little mortar, portable in the rucksack by one man, was a derivation of the most
original Stokes mortar: It's projectile had a tail without fins. Into the tail tube was
istalled a bulleted rifle cartridge (or a rosette-crimped propellant cartridge, captured
from Russians during Winter War, designed for a signal flare launching adapter,
bayonet-mounted on the muzzle of Mosin-Nagant Model 1891/30 rifle. Finns made also two
types of these flare thrower devices, but they were unable to substitute the a 4 gauge
signal flare pistols). Finnish bulleted rifle cartridge with a LAPUA D-166 bullet (weight
13 grams) had a correct powder charge (2.6 grams) for launching the 47 mm grenade, but it
was also possible to use a cartridge with Finnish S-bullet or Russian L-pulya; bullet
weight 9.65 grams and powder charge ca. 3.2 grams. The heavier charge split sometimes the
tail tube, but this incident was harmless.
There were elevation and adjustment tables for use of both D-166 bulleted and S (L)
bulleted cartridges. Last mentioned ammo gave somewhat extended range, of course.
(Original 3 inch Stokes mortar "bomb" had a 12 gauge blank shotshell in it's
tail tube and a time fuze. It was also designed to burst in flight above enemy trench, but
second generation of the mortar shells had fin-stabilization, "arrow-like"
flight and a point-detonating fuze). Finnish improved grenade for 47 mm Kranaatinheitin
Malli 1941 (47 krh -41) was no more oval or "egg shaped" but cylindrical, and
it's cast iron shell was fluted with straight longitudinal grooves. It might be stabilized
in flight like some shotgun slugs - by air resistance and mass-stabilization, a.k.a. the
"shuttlecock principle".
Unfortunately, I have never seen and held in my hand a filled 47 mm krh grenade with it's
8 seconds time fuze (of brass), but I presume that the point-end is somewhat heavier than
the tail end, generating a mass-stabilization. There were, however, presumably never tried
to adopt a "iskusytytin" (impact fuze; preferably very sensitive one) for these
grenades. Finnish 47 mm krh -41 mortar had a gas bleed regulator system on the breech end
of barrel for adjustment of muzzle velocity. It was essential, because functioning delay
of the time fuze was fixed; adjustable with no other way but use of a hand grenade fuze
(delay 5.5 seconds) instead of 8 seconds fuze. Parts of these fuzes were same, with the
exception of a delaying column, which was more long.
Unless the gas bleed apertures were all closed, the "47 mm krh -41" was very
unpleasant weapon to shoot from the prone and knelt positions. A blast of high-pressure
powder gas was able to deafen the shooter, temporarily - or permanently. As far as I know,
the 47 mm kranaatinheitin malli 1941 was never produced in quantity or issued to troops -
even during the trench warfare ("asemasota-vaihe") of 3rd Finnish Independence
War, which was mainly a trench war since early 1942 until June 1944. "47 krh
-41" was presumably designed hastily during the truce between Winter War and it's
"Continuance War" in 1941 - 44, for the desperate last stand of Finnish people.
(It was not known that Germany was a would-be ally of Finland before the end of our Winter
War. This fact is revealed by the mass-media just some months ago).
TERMINOLOGY:
The mortar is a "kranaatinheitin" - literally "a grenade
launcher", abbreviated "krh" in Finnish. Word "kranaatti"
means the explosive or incendiary shell of an artillery piece, anti-tank rifle, a mortar
bomb or even the hand grenade, if the caliber of firearm is 20 millimeters or more. If
less, the projectile is either "luoti" or "ammus".
Last mentioned word means a projectile in general; even the "dust size" single
pellet of shotgun's payload, with less than one millimeter in diameter.

MKS and durability of suppressors
1) Have you seen any articles or reports on the Interdynamic MKS rifle? It was
developed by Interdynamic AB of Stockholm as a light and compact 5.56 x 45 mm rifle. The
MKS was an unusual design, looking more like a large machine pistol more than a rifle. I
was interested in finding any type of comment on it's ergonomics, since the magazine well
was in the pistol grip!
2) I have entered a debate with one of my friends about the longetivity of suppressors,
i.e., how many rounds can you put through a suppressor before it is no longer effective to
reduce sound. My friend believes it's maybe three bursts from an automatic weapon or a
very limited number of shots through a semi-automatic weapon. I believe she is getting
this assumption from outdated information, although I have heard are some commerical
disposable sound suppressors, and the type she is thinking of are improvised silencers. I
know that suppressors used to have baffles made from wire mesh or even leather, but most
suppressors are now are made from steel, like much of the suppressors on your website or
one the SD version of the MP5.
Avery
1)
Brother of Interdynamic AB's manager is my friend. He told that Sweden is a least
possible country for export of innovative firearms: "There are too many hoplophobic
social-democrats in the administration of Sweden; no matter what is a coalition of the
Cabinet". MKS was a stillborn idea, although it was a real innovation. It was simply
born in wrong country and in wrong era of world history (just like me). The chapter about
MKS was published on the year-book "JANE's INFANTY WEAPONS" in mid-1980s. No
other information about this technically and ergonomically sound assault rifle design has
appeared to our knowledge.
2) Mild steel is truly an ideal material of suppressors, designed to be long-lasting. Some
"silencers" are really designed to suppress the noise of ONE shot only, when
just one shot is needed to "eliminate physically" some hostile individual.
Suppressors for target practice and/or hunting (where
allowed) must be designed to stand several thousands of full-powered
rifle shots and countless number of handloaded shots of true "silencer
cartridges" with subsonic bullet velocity; also known as "silent
without suppressor" (SWOS) loads. Aluminium alloys are also long-lasting, if not
cleaned with water solutions of strong basic chemicals (sodium bicarbonate; sodium or
potassium hydroxides; ammonia). Aluminium alloy baffles may, however, melt or "burn
away" entirely when the long bursts are shot through a suppressor, mounted on a
machine gun or assault rifle.
Aluminium is O.K. for handgun suppressors, but the probable material
for next generation lightweight suppressors is "Polymer 66", trade mark
"Nylon", also as the jacket material. It's molecular structure contains some
water. Therefore the lead and bullet lube fouling shall not cling on the Nylon surface as
easily as on the other materials. Strong alcalic detergents are also "poison" to
the aluminium. Entirely non-metallic suppressors are maintenance-free if the baffles are
designed to be "self-cleaning". Powder charges/ muzzle pressures should be low.
Non-metallic suppressor is good for firearms shooting .22 Rimfire non-magnum ammo,
preferably subsonics.
Mild-steel suppressor (BR-Tuote) was once shot red-hot with a Finnish M 62 assault rifle; 30 rds bursts. Pauses between
them were no more long-lasting than the magazine changes (less than five or six seconds).
Firing was continued until the first fault was noted from a suppressor: A welding seam was
slightly hair cracked. Accuracy of last bursts was also somewhat deteriorated, but it was
not a sign of faulty suppressor.
Bore of assault rifle was simply destructed unserviceable by the heat of shooting. The
cracked seam was welded again, remnants of the burned paint were brushed away and
suppressor was painted again. Then the suppressor was sold to a customer who was willing
"to buy a proof-tested suppressor". (Today are BR
suppressors Parkerized, i.e. iron/manganese-phosphate coated; no more painted).
Similar endurance test was carried out several years earlier for Finnish VAIME suppressor
(with cast aluminium baffles) in Namibia by a gunwriter and firearms designer W.A.
HUNDT. Test gun was an assault rifle, caliber 5.56 x 45 mm NATO. After shooting ca.
200 shots of full-auto fire, there was noted a heavier than usual recoil "kick"
and a big bright bluish-white fireball flashing from the front end of suppressor, which
turned to be a megaphone. Aluminium baffles were burned (almost exploded) away without any
sign of danger beforehand.
New Finnish JET-Z (AU) suppressor is not yet endurance tested, as far as I know. It is
designed to stand most horrible .30 caliber Magnum charges, loaded by
"kamikaze-handloaders" with too slowly-burning powders along with
recommendations of VihtaVuori. In the rifle with shortened barrel (Finnish allowed minimum
barrel length is 400 millimeters) may just 80 per cent of some "slow" powder
burn inside the bore and 20 % from the charge burn inside the suppressor. JET-Z suppressor
is about twinfold as expensive as BR Telescope Reflex suppressor with similar performance,
because it's baffles are turned and milled from a solid steel bar-stock to somewhat
complicated shape.
"Test-shooting of BR muzzle-can for Russian Maxim-Sokolov.
Finnish test-shooters starts their career in young age. This boy was three years in age at
the moment of photographing and therefore somewhat flinchy."
For the endurance test of JET-Z may be needed a water-cooled MAXIM machine gun and MANY
200 rds belts filled with 7.62 x 54R cartridges. A risk is that the Maxim shall become
ruined rather than JET-Z. When a BR suppressor was mounted on
the muzzle of a Russian Maxim gun, the rate of fire was increased from inherent 450 - 500
rounds per minute to almost a thousand rpm! JET-Z has somewhat smaller inner volume than
BR's muzzle can for Maxim, and therefore it may be still more efficient "muzzle
booster". There is also another perpetual problem: "Who pays the test
cartridges?"

Valmet 412 monoblocks
I own a Valmet 412 with 28 inch 12 ga. barrels. I 'm curious to know if monoblocs are
available to make up a double rifle barrel set in .416/.500 (yes, I know it's a large
bore, but my retirement plan stayed in South Africa when I moved back to the U.S. in 1994)
which has gotten good reports as a buffalo killer. Many thanks.
Regards. John (American-Finnish).
Finnish SAKO
Oy has been distributor of Valmet 412 since the late 1980s. Today Sako is a part of
Italian BERETTA company and distributor of Beretta shotguns, but Sako Oy may have spare
parts for Valmet 412 still available. The e-mail address of SAKO is export@sako.fi .
If the monoblocs are no more available (they were made in Italy during the many years
before Beretta-Sako fusion), ask for 9.3 x 74R spare barrels for your 412. This 101 years
old German "9.3 mm FORESTER" cartridge is also a fine buffalo (and even the
elephant) killer, when loaded with a Full-Metal Jacketed bullet, shot on the forehead of
attacking buffalo or on the ear-base (aural orifice) of a buffalo from the side. DO NOT
try to kill it with a hit through lungs or heart! Those hits are fatal, but the Cape
buffalo shall toss you death before it's own death. And NEVER trust upon the effect on
anything, but a FMJ bullet or a non-expanding projectile of SOLID copper, brass or iron
(mild steel).
A well-known Finnish gunwriter TIMO HYYTINEN tried to kill a Cape buffalo with a famous
Sako Hammerhead bullet, but the buff didn't even note the hit. It became furious (not from
the hit, but a blast of a rifle) assaulting towards Timo. His hunting companion was -
fortunately enough - armed with a 9.3 x 74R caliber double-barreled rifle, loaded with RWS
cartridges "mit Vollmantel Geschossen" (with Full Metal-Jacketed bullets). Just
one hastily pointed shot stopped the attack of furious buffalo, although it hit ca. two
inches below it's eye. It was not a perfect hit, but good enough to kill a buffalo
immediately.
I have seen many times the stuffed head of that "Cape Longhorn" on the wall of
Timo's home - and photograph of it on the Sako catalogue, or periodical hunting magazines
on the advertisements of Hammerhead bullets. Jess, the very first hit through lungs of the
buffalo was shot with a Hammerhead, but rest of the story was entirely different.
Instructive? I hope so!
PS. To the visitors less conscious of zoology: The Cape buffalo is entirely different from
the American bisons, which were slaughtered almost to the extinction with .44 Henry rifles
and even the percussion revolvers. South-African buffalo is able to fight back - and it
knows the term "revenge".

You may find
Cyrillic letters from some (if not any) encyclopedia. Headwords are:
"Alphabets", "Cyrillics" or "Russian language". Numbers are
similar to those in Civilized/ Western world. Code letter(s) and numbers are in the single

Drift Chart for a Whitworth Rifle
Do you know where I can find a copy of the drift table chart for a Whitworth
rifle. I heard it came with the gun when sold back in the 1860's?
Danny
Sorry, I
dont know, but I hope that some of our visitor possessing this card is kind enough to send
the text of it to us or copy of it by e-mail or to our P.O. Box. The Whitworth Rifle,
rejected by British Government, but adopted for sniping by Confederate States of America
during the lost Independence War of CSA is very interesting piece of equipment.
There is some information about comparative shooting tests of .577 caliber Enfield rifles
versus .451 caliber Whitworths (still muzzle-loaders. Sir JOSEPH WHITWORTH designed also a
breech-loader variation especially for export to CSA), on the book "GUN AND ITS
DEVELOPMENT" by W.W. GREENER. Difference of accuracy was amazing! Some Whitworth
rifles of CSAn snipers were equipped with scope sights. The bullet hole on the death body
of Yankee General SEDGLEY was probably small, and hexagonal in shape. His last words were:
"Those f..king Rebs can't hit even an elephant at this dist..!" (800 yards!) You
may see that we have eager interest in old hexagonal-grooved military rifles and artillery
pieces with mechanically fitting projectiles.

Stock carving of Finnish M91 rifle
My excellant condition Finnish M91 rifle on a Remington receiver has the initials E.K.
rather crudely carved into the left butt, looks like the work of a bored soldier who had
no fear of retribution by his sargent. Others I have spoken with have similar markings on
a few rifles, such as E.R. etc. Could you comment on what these are?
Best Regards, Sam
Carving
is presumably done by some individual. "Official" markings of rifle stocks were
burned with a hot brand iron and they were never crude. Most usual brand was a letter
"S", with three lines above them and usually surrounded with an escutcheon. It
was a brand of Suojeluskunta = Finnish Civil Guard. Some unit brands were also
burned or impressed with the steel stamps, but never carved, as far as I know. Crude
carving may be done during Finnish Independence War/ Civil War/ Red Rebellion in 1918 by
some private of the Red Guard, which was equipped with Mosin-Nagant M91 rifles too.

PPSh 41 manufacturer
I have a PPSh 41 manufactured in 1953 in an Eastern country. The code on the receiver is
11 (eleven). Would it be possible to know which country it was? Thanks for answering if
you can.
Daniel, Switzerland
If the
code stamp is encircled with a circle, looking like a rifled gun muzzle, your PPSh is made
(or assembled) in Bulgaria. In the Bulgarian factory number 10 assembled and finished 9 mm
Makarov pistols are of very good quality. Unfinished parts of them were presumably
imported from Soviet-Russia. Some other Communist Block manufactures could, however, also
stamp their products with factory codes only. Polish Radom is said to also have used
number 11 inside a plain circle. The "gun muzzle" stamp around figures 11
designates the Bulgarian production.

Chatellerault rifle MLE. 1892
I am looking for any information I can find on the weapon mentioned in the subject. The
only information that the owner supplied is: Chatellerault MLE. 1892, MA-C1897, Serial
[?]: 95127
Specifically we are looking for where it was made, where it was used, how much it would be
worth on today's market [just a guess], what calibre it would be [or what calibres were
available]. Anything else that you would deem important would be helpful. I await your
reply and I remain:
Gary
Manufacture
d' Armes de Chatellerault was (or is) a French firearms manufacture. It designed one
famous light machine gun and a tank/fortification machine gun with 150 rds drum magazine;
not the rifles, but it produced rifles designed elsewhere, including a lot of Belgian
& Russian Mosin - Nagant Model 1891s, until Russian firearms manufactures were
tooled-up to yield them in Russia.
Modéle 1892 rifle (or a Mousqueton Artillerie, with a shortened barrel) was
designed by French General A.V. BERTHIER. It has a three rounds box magazine instead of
tubular magazine of contemporary LEBEL Model 1886 rifle. Caliber is 8 mm Lebel (only);
presumably no more available. Forget the shooting if there are Mannlicher-type three round
clips (chargers) no more available. The magazine is unable to feed cartridges without
those clips.
This musketoon is made in 1897. Estimated collecting price of the musketoon is US $ 300:00
in "NEAR MINT" condition and USD 200:00 if the wooden parts are slightly
battered and the original blueing is worn away from corners of the receiver. There is a
story about Berthier rifles, musketoons an carbines published on the GOW/Universal on some
old Kickback Q & A chapter, but I am unable to tell, which one.

"Long case" problems of .30-06 subsonics
I have tried some loads, and are working with the information on the web. I have tried
some loads for my .30-06, but encountered some problems. First I shot over my Chronograph,
and then later I noticed some terrible vertical stringing when using the 150 grs Lapua
Lock Base bullet. The hits separated in two "layers" (hi and lo) about 1 ft
apart. Maybe the velocity was marginal or the bullet too heavy? I will try some loads also
with the 123 grs S374 bullet to see if that looks better.
Well, I will tell you more about my testing later.
Sincerely, Lars (PV), Norway.
Bullet weight
150 grains was and is a standard projectile weight for .30-06, although original cartridge
.30-03 had still a round-nosed bullet of .30-40 Krag, with a weight 220 grains. Rifling
twist of .30-03 and .30-06 rifles (1 - 10") was chosen for stabilization of those 220
grs projectiles. It is steep enough to stabilize any & all bullets with a lead alloy
core, weighing 150 grs, at all possible muzzle velocities.
Your problem, a "two groups mystery", is usual when cartridge case length is
more than 51 - 54 millimeters and when the powder charge of subsonic load fills less than
1/3 powder space of cartridge. Name of the game is POWDER POSITIONING: If you shoot - say
- five rounds of cartridges with the powder charge in REAR END of the case (close to the
primer's flash hole) and another five shots with cartridges having the powder charge in
MOUTH END of a case (close to the bullet base), you'll get two small groups on the target
at 100 meters range. Dispersion of hits may be less than one minute of angle (less than 30
millimeters at 100 meters) in each group of five shots, but the group may be 300
millimeters or even more separated from another group, usually over and under.
A Chronograph shows not alarming extreme spread of bullet velocities, but you must
remember that vibration of rifle barrel starts from the very moment when a hammer or
striker of a rifle is released from grasp of the sear. A millionth of second delay between
hit of firing pin and ignition of the tiny powder charge may cause considerable vertical
dispersion of shots, because the barrel is vibrating and in the worst possible case it is
bent muzzle upwards when a bullet emerges and muzzle downwards when another bullet
emerges. Amplitude of barrel vibration may be very low, but mere five minutes of angle
upwards AND downwards means almost a foot of vertical distance at 100 meters between the
centers of separate groups, if some bullets starts from muzzle which is on the topmost end
of vibration and some other bullets emerges from the downwards bent muzzle.
If the position of powder charge is always same, the delay between firing pin hit and
ignition of powder charge is always equally long. Barrel is also bent always as much and
towards the same direction, when the bullet leaves muzzle. "Name of the Game is THE
SAME" is a common slogan of bench-rest shooters. They have no problems due to the
variable powder positioning, because they'll cram their cartridge cases full of rifle
powder. Shooter of subsonic rifle cartridges must keep in mind some special tricks of
powder positioning, until some cartridge case manufacturer starts production of
plastic-lined shells with considerably reduced powder room. (LAPUA: "Never!"
SAKO: "Never! Not invented by OUR ingenious cartridge designers!").
A well-known trick is use of "disposable case filler", a wadding of some fibrous
material like cotton, kapok or Dacron. Some friends of mine use a disposable ear-plug as
an over-powder wad in subsonic .308 Winchester or .30-06 and 7.62 x 54R Mosin & Nagant
cartridges; also those loaded for suppressed rifles. Dacron fibres are recommended for
them, because they'll melt easily by heat of powder flame. Remnants of Dacron (a tiny bead
of solid polymer) shall fly out from the muzzle behind a bullet, and also through a
suppressor.
Ideal wadding material is, however, self-consuming "collodion wool": Cotton
nitrated to 11 % content of nitrogen, bound in NO2 molecules. The first polymer or plastic
(Celluloid) was made from collodion wool, which is rather inexpensive material. Because of
it's fibrous structure it burns about as rapidly as the best brands of smokeless powders
recommended for subsonic rifle cartridges, leaving no solid or corrosive residue. But it
is, of course, unavailable to the common people - although collodion wool is completely
safe to store when moistened with water and actually less dangerous to handle than usual
gasoline, which is available to anybody.
Use of wadding, including a foam-plastic ear plug, shall retard the handloading procedure
of subsonic cartridges. There is fortunately another way to position a little powder dose
in the cartridge case, known in Finland amongst the target rifle shooters as long as the
smokeless powders are used in the handloaded cartridges for target practice. (Since more
than a hundred years ago!). Some old riflemen had still in my youth a rite-like habit to
erect the rifle muzzle upwards (despite of shooting range rules) and "slap the girl's
butt" with a palm of hand. This rite was from force of habit, a way to settle the
powder charge to the primer-end of cartridge, already needless but impossible to weed out.
Next generation of riflemen did no more learn this rite, and it was forgotten - until
needed again, almost 20 years ago, when the use of subsonic rifle cartridges became
introduced in Finland. It is also possible to settle or position the powder charge into
the frontmost end of cartridge before slow and steady movement towards the target. It
makes no difference, whether the charge is leaning on the bottom of a cartridge case or on
the bullet's base. But it is ESSENTIAL that the powder is about in the same place in every
cartridge just before the shot.
In hunting situations or during other "field activities" the available time may
not allow positioning of powder. For these special purposes are cartridges with
over-powder wadding "must". On the target range is shooting not as busy,
especially with subsonic cartridges, and therefore the old trick of target shooters,
settling of the charge, is still or again applicable.
PS. I must apologize the excessively long delay of my answer. "Ukko Ylijumala",
also known as "Perkunas" or "Thor" (deity of the
thunder), brought about a blackout of GOW sites and still more long-lasting interruption
of email. A stroke of lightning slayed also an 18 yours old boy not far from our rural
"telegraph office". There were registered 7000 strokes of lightning reaching
from cloud to earth during one storm and three consecutive thunder storms during the same
day.
Hot humid weather has been like the climate of South-American jungles. I like a room
temperature 17 degrees Celsius; not 33 degr. C, which I feel "somewhat
incomfortable".
