In the M1A I loaded 39 gr. IMR 3031 shooting the Sierra # 2200 168 gr. Int. Match BTHP using a LC military match brass.

That load was very accurate in a .308 heavy barrel bolt match rifle as well. I also used the same load in a .308 Rem 700 with the Hornady 165 gr. Spire Pt. for hunting.

That has always been an accurate load for me.
