I have had good luck with imr 4350 and 4831 with bullets over 85 grs, I have had great luck with Hy-brid 100 in bullets over 85 grs. In lighter weight bullets I have a few loads with imr 4320, and a few with rl 15, and varget. The4320 has had some real good groups, velocity is middle of the road. Been tempted to try RL 17 but haven't as of yet.
