vonn, as I remember the loading data from when I reloaded for my M1A and M1MKII, Sierra data listed the 165gr GameKing with the 168gr HPBT/International. Unfortunately, I never used H4895. When I replicated M852 and M118, I used just over 42.0gr of either AA2520 or Varget. For the '06 when I replicated M72, I used IMR4895 and IMR4064. Working off of the Hornady data, 42.5gr of H4895 with the Hornady 165gr hunting bullet will put you in the ball park of 2550 fps safely.
