Great load for your M1-A!
I was shooting my new Springfield Match Grade M1-A (.308 Win.) at a Ft. Benning Match several years ago with GI Ball ammo........an older retired Army Vet came over to look at my new acquisition......He said "Son I am going to save you a lot time and expense on working up a load for that new piece you got there." He handed me a 3x5 card and on it (hand written):
168 Gr. Sierra BTHP
39 Grains of Hodgdon H322
CCI Match Primer
I checked the load in my manual, then loaded up 25 rounds.........Well the old Sgt. was right on........the load in my rifle was a tack driver!.....Have tried lots of powders & bullets, nothing shoots any better............enough! Thanks, W.T.
