Master Po's comments

These loads only duplicate military spec. velocities for the given bullet weight, using commercial cases and powders. If you are using military cases, drop all charges by 2 grains.

If you are looking for accuracy, drop all charges by 1 grain and work up .2 grains at a time.

Master Po's Ancient M1 load secret

This is my personal M1 load I use in my CMP M1. It will shoot better than Master Po can. I worked this load up, as you should for your own rifle.

Remington .30/06 cases, flash holes deburred and weighed within 1 grain.
Federal GM210M Primers (Master Po has heard the horror stories of Federal match primers in the M1/M1A rifles. If you're squeamish or new to reloading, use Winchester Large Rifle)
47.0 grains IMR 4064
Sierra 175 grain MatchKing
Overall length 3.340 inches

This load, in my M1, duplicates almost perfectly the M72 match load specification with a very low standard deviation. Groups off the bench run 1 - 1.5 inches with the original 1945 barrel on the rifle. Of course, Grasshopper YMMV.
