I respectfully disagree. I don't know if you've ever heard of op rods being damaged by overpowered hunting ammo but I know someone this happened to. During the covid drought when guys were buying whatever was left on the shelf he picked up some 220gr monster moose ammo that should never have been near a
Garand
, with or without an adjustable gas plug. One round and his op rod bent in 3 places. The bolt was slammed to the rear of the receiver by popping out of the op rod channel. The front handguard was cracked by the bent rod but he epoxied that. In all it was a very expensive lesson that nearly ruined his 1943 SA.
I had to break down those rounds for him. I added 150gr fmj's and repowdered them to M2 spec. I loaded up those 19 220gr heads for my Krag.
No your not going to blow up the barrel but the gas system can easily be damaged by hunting ammo overpowered beyond the gas systems design specifications. I'm sure his wasn't the only Garand damaged this way.
