the M1 carbine was built to higher standards than a lot of guns you see today. some AR15s with poorly made budget parts may snap extractors on steel cases and cheap magazines with plastic followers may have the follower shaved down by steel cases but the 30 carbine does not have any of those problems. wolf is cheap, dirty, nasty stuff and many guns don't like it for accuracy but my AR15 is actually most accurate with wolf as far as plinking ammo goes and it has yet to skip a beat. my XDMs and MLE45 have had a pretty steady diet of steel cased ammo and had no ill effects.
