Id be real hesitant to use a stout load of a slower powder like that in an Unmodified Garand. Op rod and gas system react to slow pressure curves way different than a modern bolt action.r700 3006 with h4350. Has very small pressure mark on the case head with 56.8 at 3.402 oal. .8 moa all day long
Ive used a mild load of imr4064 like 47 grains with a Sierra 155 hpbt with some success.
