It is unique. The cartridge is the only straight wall rifle round.
Straight wall means not necked. Almost all so called straight wall cartridges has some sort of taper. 9mm has 0.011", 40 sw has 0.001" , 45 acp has 0.002".The .30 Carbine cartridge is hardly the only straight wall rifle round, and in fact isn't a straight wall case at all. It tapers .023" from base to mouth.
The M1 Carbine is unique in a couple of ways, no one else fielded anything quite like it during the war, and, while never intended for frontline combat, it was very popular with combat troops, because of its size, light weight, magazine capacity, and light recoil. It was effective enough, particularly when "backed up" by other weapons, and had enough range for many combat situations.
As I recall, Audie Murphy was rather fond of his, and used it well....
ITs not a perfect rifle, but it was good enough for a lot of GIs at the time, and that creates a bond that overlooks a lot of flaws.
part of the problem was the Army at that time was not teaching very good pistol combat shooting techniques. They taught mostly the off-hand (one handed) technique that was popular during that era for target shooting not combat.The other concern was that in that way, those issued pistols proved to be not quite the "dead eye dicks" of legend. Those hardy descendants of Old West gunfighters simply couldn't shoot a pistol!
My apology, Peggysue. I looked it up and you are absolutely correct. The marines actually trained the army units and spear headed the landing operations. I just didn't know, now I do. Thanks.Tangolima I am upset on you questioning me...even google has info on this...My father was a Seabee and landed at N Africa to support the Marines.
I wonder what other center fire straight wall rifle cartridges there are. Rifle cartridge means cartridge that was originally developed for rifle use.
Or just an M1 chambered in 45 ACP. COuld still be semi-auto. Or a modified Sten. The gun isn't all that important in the logistics. Hell, think how amazing it would have been if they did a 1911 carbine conversion/variant. I just don't get introducing a new cartridge in this case. I don't think anyone else did that. Yes, the .30 Carbine has a bit of an a ballistic advantage over 45ACP, but not enough to justify it IMO.Are you thinking along the lines of the M3 submachine gun?
