.. has turned out to be IMR 3031 surprisingly. I don't remember finding any load data on it, and ran across 20 cases that I loaded in July according to my data card with the batch....
28 grains with 90 gr Noslers, 120 gr Sierra HP Match, 123 ELD-M, and 140 grain Speer SP...
shot them at the range this afternoon, 5 shot clover leafs....I'm still thinking I might have to back the 140 grainer back a bit, but am reloading those cases
tonight and will check at the range tomorrow....
haven't chronographed it yet, I assume MV will be pretty close to H322 velocities...
