RL 25 works well as does Rl 22. Max velocities can be obtained with Rl 22, but H1000 is more stable in temp extremes. My old barrel used to like 94 gr of Rl 22 with 225 NAB at just under 3200. H 1000 only yields about 3100 max with a full case of powder. 95 gr of Rl 25 gives good results with 250 gr partions at 2970. Imr 4350 will work, but doesn't fill the case enough for my prefferance.
