Well did a stupid today. Took out my new-to-me Universal M-1 3rd Gen to the range and picked up a couple of boxes of Tula FMJ just to test the new magazines and such. Well about thirty rounds started having FTE (Fail To Eject) and stove piping then a stuck expended round in the chamber.
Immediately took it to the range Gunsmith and his first comment was "Don't use lacquered rounds in your M1."
I'd never given it a second thought when I bought the ammo, as I'd never had a problem in any other of my military styled rifles. I know....I know...stupid of me. The Gunsmith said that he'd even had the steel Russian rounds break extractors and that I should stick strictly to brass only ammo.
So heads up to Newbies to the M1 Carbine world like me.....NO RUSKIE AMMO!!
