won't damage anything if the gun is o.k.!!
if you couldn't use factory, what would you use?Military and factory ammo aren't much different in power, but the new factory ammo will probably be better quality control, and definitely not corrosive.
The garand is a very strong gun, and shouldn't even flinch with factory winchester 150 grain ammo. Bet you will though.![]()
My former reg force father in law, gave my son about 300 surplus M2 ball rounds he picked up when they were cleaning out the ammo locker years ago. Saw the same boxes of ammo at a gun show in Winnipeg a few weeks for $ 45/20. Goes bang just fine. Could probably sell some and make some cash but no we'll just pound till it's gone.
