In the heyday of the 308 in match rifle competition, 40 to 44 grains of imr4064 was most popular with Sierra 168's.
Same for Varget a grain or so less will equal or better it.
Ball powders never cut the mustard constantly enough.
I agree Bart,
4064 was my go to powder at the time till i started using VihtaVuori
In the heyday when i used to shoot 308 in comps,i had excellent results with VHT 150 and 550 also.
my loads for 168smk where 41.5-43grn of vht150 or 42.5-45.0 of vht550
