Varget lot to lot veriation

[Baer45]

I've see slightly better accuracy with IMR4064 but it's more sensitive to temperature than Varget.
Here are some loads that seem to work with the .308. Slower works better for me. I have a 22" 1/10 barrel and set the jump to .025". These , if I do my part, will shoot at or under 1/2" at 215 yards.

Hornday 168g Match or Sierra 168 M/K:
IMR4064 41.7 grains (about 2,570 fps)
Varget 42.2 grains (about 2,580 fps)

Hornady 208g A-Max or ELD
41.5 grains Varget (2,430 fps)
