That was a consideration when I purchased my M1A.
It will shoot whatever you feed it, with no danger.
Not quite right, if you use a heavy bullet the action can unlock before the bullet exits the barrel causing a Kaboom. At least one freeper has blown up his M1A, I remember reading his story years ago. I later learned about how that happens.
I love the M1A but I have limited my shooting to military ball or light weight .308 rounds.
