The Swede rifles I load for, Ruger 77 and Winchester 70's and from 46.5-48 grains of RL-22 top out 2,800 to 2,850, depending on powder lot. That is about the upper limit with any 4350 I have used, or H 4831, for that matter. I arrived there by graphing out velocity increases and charge wt increases. The 2,800 fps level seems where the graph curve begins to flatten out. Everything works and I have no desire to push that any further, mostly because I see no need.
