I did some shooting tonight after work, of several different charges of H322 I settled on 21.3 grains under these Sierra 65 grain Gamekings. Group size seemed to increase as powder charge increased. I averaged an inch at 100 yards, not bad for a 16" barrel and a 4 power scope. I plan to load another 20 rounds and shoot with a clean barrel to be sure that's the load I want but so far 21.3 grains if H322 is looking like it. Hard to tell what the velocity is, but judging by the figures I see from Hodgdon I'm estimating between 2725 and 2765 fps? This should be a pretty nice velocity for this bullet, and the cases aren't being worked hard pressure-wise.
