I recently sold my WW2 Inland M1 carbine for top dollar because everybody seems to want one for a home defense gun. I had fun with mine, but wasn't crazy about it, so when I got the right offer I sold it with no regrets. However, I still wanted some sort of rifle which could exploit the .30 carbine ammo I have in abundance, as a companion to my Ruger revolver, in keeping with what I call "The Harry Archer Protocol."
Objective was to have a light, compact take-down, backpack rifle to accompany my Ruger Blackhawk in .30 M1 carbine, which can also digest .32-20 rounds. The resulting barrel installed on the Infamous Bunny Gun, just back from John Taylor, weighs 5 pounds and is 36 inches overall when assembled as shown here.
Barrel was turned down from a WW2-era Browning machinegun barrel and is of 4-groove, government form, .308 groove diameter with one turn in ten-inch twist. Chamber is standard for the .30 M1 Carbine, except its being long-throated like an '06 for 174-grain Ball M1 or M72/M118 pulls seated to the cannelure on the Ball M1 pulls. A nominal case full of IMR4895, gently compressed in the same manner as loading black powder is subsonic and stable.
A rim seat was cut in rear face of the barrel to permit expedient use of .32-20 ammo. The rifle will positively eject either rimmed or rimless rounds. Accuracy should be better than the US carbine based upon previous testing loading jacketed carbine pulled bullets, firing them in the .30-’06 with same throat, rifling form, twist rate, bore and groove dimensions at similar low velocity. The smaller M1 Carbine case, having less capacity should be less sensitive to powder positioning also.
Barrel breech is machined to receive a US M1 carbine rear sight. Muzzle has integral base machined for a US M14 front sight. A half-rail with Picatinny base is installed onto the barrel, affixed with epoxy and 3 screws to permit scope use for load development.
Barrel length is finished at 21 inches. Overall length of the rifle is 36 inches at 5 pounds.
Full range report to follow when able.
