Saw that done with M1s numerous times. Never saw nor heard of the problems schutzen-jager mentions. Had a couple Ranger delink 400 rounds of M60 7.62 NATO 4-1 rounds and fire it through a couple M1918A1s (BARs) w/o any problems. Only problem with that was the ASP wouldn't take the brass back. Had to FL size the cases for turn in.....
