What ammo can I shoot in my M1?

Question

I was told I have to shoot M2 Ball ammo in my garand.  Why can't I shoot other ammo?

Answer

The M1 was designed around M2 Ball ammo. Current ammo has too much pressure and can bend your op-rod.  To shoot new ammo, you need to get an adjustable gas plug that lets you bleed off excess gas.
