M1 Carbine in an intermediate caliber

[RCS]

I always wonder if US Ordnance gave any thought to the Winchester 35 Self loading Cartridge for the carbine, they did use the smaller brother, the 32 WSL cartridge. With a 150 gr bullet these fit right into a carbine magazine. this 35 WSL is nothing more than a rimless 38 special case (like the 38 AMU pistol cartridge) plus you can still get a good velocity with a heavy 35 cal bullet

So we had 30.06 and .45ACP as standard infantry calibers. You really think it beneficial to adopt a third completely different caliber along with the related tooling required during a time of war?

That was a common string of thought and I understand the .276 was shot down for that reason, but they went against that thought of caliber commonality when they chose the 7.62x33 round for the carbine anyway……a third caliber.

A third cartridge, not a third caliber and diameter. When the specifications for a new Carbine were released for development .30 caliber was specifically required due to the issues of tooling and some commonality. McArthur personally "shot down" the .276 specifically due to the millions of 30.06 already in inventory.
