My two Garands like...
what was passed on to me as the old National Match load, a 168gr MatchKing, and 45.5 gr of IMR4895. Primers are Federal 210 Match, brass is Lake City '68.
As usual, work your way up to a given load, using a recent loading manual as a reference. But for the Garand, do stay with IMR 4895 or powders that duplicate it's burn rate, otherwise gas port pressures may be off enough to harm the oprod and action.
"Bother", said Pooh, as he chambered another round...
