I think I asked about this a while back, and learned that modern loads designed for commercial rifles are a bit too strong, use slower burning powder, and heavier bullets than the M1 Garand was built to handle.
When I got my M1 after selling my 30-06 bolt action, I gave the full box of 180gr shells with the rifle and the half used box to GunGeek. I think that Amerivcan Eagle loads are ok for the Garand though.
Just speaking from my own experience, I wouldn't use any projectiles over 165-grn. Most commercial ammunition designed for both bolt, and gas guns will work. But, as I said, stay away from the heavier bullets. Don't wanna warp an op-rod!
Stockwalter, All modern ammo is hard on a M1, all you need to do is get a McCann adjustable gas system for your rifle and you are good to go...You can shoot any ammo you want to, I put one on mine and it works like a charm...You can find them at www.brownells.com part #100-000-402 Happy shooting...:assult:
