Thanks, RH, I'm going to try that. My 44 grain load of Varget produced 2800 fps (900 ft ASL) SD 4, ES 9 but a .7 moa group, again this was with the ELDM. I've tried 42.1 of IMR 4895 and found it extremely accurate but that powder is not as temp stable as Varget.

What was the velocity of your 41.2 grain load?
