After finding so-so reports going both ways about the Malaysian surplus 7.62 and the M1a, I figured I would try it and report for the next guy.
So the good news, I ran 40 rounds that came packed in the .50 cal ammo cans through my new Springfield M1a standard and all fired reliably and ejected with no problems. Accuracy with that rifle was about 2-3moa using iron sights at 100 yards.
Also ran some through my FAL and they cycled with no problem, same thing with the PTR91 A3S.
