I'm getting very similar results and good accuracy. M1 Garand level loads at 46/47 168/155 loads with AA4064. AA2495 (4895 similar) didn't group as well for me, but gave safe and effective loads. Was lights out in heavy match .223 and a couple of odd medium burn applications. IMR4064 has been my grail for a long time in the M1, and the AA version is serving me well. Saving the IMR version for obsolete cartridges with limited data. The Sprgfld and M1 are eating AA4064 going forward including serious matches... Have a state championship 3 gun M1/Sprgfle/Vintage aggregate to defend, and possibly Perry next year. AA4064 is GTG!
Edit. Meant to quote this one from .45 coltguy.
"I have read/heard, that AA4064 is very close to IMR 4064. I will be looking into this as the IMR powders are sometimes hard to find and expensive.
Luckily, my lgs has it."
