I have some AA2015, so might try it. Pressures and velocities seem pretty comparable to AA 2460 and 748 in Lyman's manual, and I have several boxes of 85gr Speer BTs.
edit: Lyman's pressure is in CUP, so 48K CUP roughly translates to 54K PSI, maybe a little over recommended for gas guns
AA2015 and H322 are very close on the burn rate charts, Benchmark 2230 and 2460 are a tick slower
