Sierra, Hornady or Berger over 75 grains preferably the 80 grain or heavier. Some guys chamber without throating for the heavies in the fast twist barrels. If you need to, have it throated to hang the bullets out there so you still have room for powder. The 7 twist LRPV will shoot 80 smk's @ .5 moa + or - at 300 with R15
