I am leed to believe the only issue with the M1 Garand and Modern loads is the excess force developed, can bend the Op rod as well as create cracks in the reciever heel.
A common option to make the M1 a litte more ammo friendly, is to use a Schuster adjustable gas nut. They are about $45 USD.
Even with the gas nut some very high pressure rounds should still be avoided.
where buy Schuster adjustable gas nut. They are about $45 USD.
there are some on EE right now, not schuster but same idea.
"So are we just gonna go in there and kill em?"
"No, I'm gonna ask them some questions... then we're gonna kill em"
