One of my favorite knock-about/ utility guns. It fires
my favorite pistol cartridge (.45 A.C.P.) Out of a light handy carbine, and
it even takes the same magazine as the classic Colt Government Auto. It is
an exceptionally fun gun to shoot as are the equally handy lever action carbines,
and the 10/22, the M-1 Carbine,
and the almost identical 9mm Camp Gun. The
gun is much easier to hit with and far easier to shoot than the .45 pistol,
but, sadly, the designers decision to go with an unlocked blowback operation
has nullified much of the longer barrels ballistic advantage. The stubby
.45 auto cartridge is very efficient when loaded with fast burning powders.
In the average 5" pistol barrel, the fast burning powder is almost completely
burned when the bullet exits, meaning that in the longer barreled carbine,
the bullet can actually be slowed down by barrel friction. The usual cure
for this type of thing is to either increase the pressure or go with a slower
burning powder, unfortunately an unlocked action does not lend itself to
slow powders or higher pressures. This type of action is generally used for
low powered pistol cartridges, and .22 rifles. It works in this particular
rifle because Marlin has made the bolt rather heavy, depending on inertia
rather than a locking action to retard the bolt's rearward motion. This is
perfectly fine as long as standard loads are used. In the case of a higher
pressure load, the bolt would be slammed back into the receiver very quickly,
before the cartridge has left the barrel. In the case of a slower burning
powder, the powder will still be burning as the bolt opens. In either case,
the result is the same--a face full of hot propellant gasses and a possible
burst case.
Deficiencies aside, this is a great all around gun, and
the heavy .45 is no slouch out of a long or short barrel, at close range.
If some one had possessed the wit to produce this gun in the forties, the
M-1 Carbine, which was designed to replace the .45 auto in issue to non-combatants,
would not have been necessary. The .45 carbine that did exist at the time
was the famous Thompson. A comparison of the two guns is interesting. The
Thompson also fired from an unlocked bolt. The earlier versions used a closed
bolt, and firing pin, the later, M-1 versions fired from an open bolt with
the firing pin milled right on to the bolt face. The Thompson weighed 11
½ pounds, and was 42" long. This makes it almost twice the weight,
and 7" longer than the Camp Gun. As much as I am a fan of the .45, the Thompson
is just too big and heavy for this round. At the same weight you can get
a Garand, firing the capable 30-06, or one of the excellent .308 assault
rifles. Even the .223 cartridge, which can be had in the six pound M-16,
and is very light for a rifle round, greatly exceeds the power of the potent
(for a pistol) .45 A.C.P. As with all carbines, the gun is very cheap for
the hand loader to shoot. Group size at hand gun ranges is under two inches,
at the 100 yard rifle range, a five or six inch group is about the best that
this gun can do. In both cases this compares poorly to a regular rifle, but
is as good or better than any thing the pistol can shoot. Overall, I like
this gun a lot; within it's design range of 50 yards or so, you can comfortably
hit anything you aim at. The gun is quick to fire and quick to reload, and
there is little perceived recoil.
