Ok, I know I posted this before, but I finally got the numbers right. My friend has a stash of handloaded .30-06 and I was wondering if it would be soundly safe (not just marginally safe) to use in the Springfield M1 Garand I'll be picking up this weekend. The load is: 47gr of 4320 powder with 180gr bullets. My stash is mainly AP, but I do have some military tracer, Remington 150gr and Win 180gr ammo. Would any of that be good or bad for the Garand? I want to treat the old boy right. Also want to know what's the best bulk ammo to buy. Would the steel cased Barnaul be good or bad?
