Nice. Imr4064 has been my go to (very close to varget in many cases) in the 22-250 and 22-250ai for a decade and a half. Several 14 twist barrels have shot into the quarter inch range with 40s.I helped a new reloader load up 50 rounds of 6.5CR for ladder testing. I also helped a friend load 50 rounds of 270 for ladder testing. Next up is 22-250 to dial in my powder charge, then bullet seating depth. BTW, Varget outperformed H380 with 52gr pills. That was surprising. Varget gave me a .65 MOA 5 shot group. H380 best group was over an inch MOA. Them whistlepigs are going to be in trouble!
