I love the M1 carbine but saying it's the ballistic equivelant of the 357 magnum is a stretch imo. 347 magnum 125 grain bullet fired from a 20" barrel = 2350 fps, 30 carbine 110 grain bullet from 18' barrel = 1990 fps. 360 fps avg with a wider heavier bullet is a lot.
Typical commercial .357 magnum is going to be moving at about 1800-2000 fps from a 18" barrel. See this chart:

You can get .357 going faster and approaching .30-30 performance with rounds from Buffalo Bore (or by reloading your own), but it's not really the same thing.
These views are not representative of those held by the US Army, DoD, or US Government.
