Re: Powder advice needed
If I were you I would use 2 different powders, Varget for the 308 and H4350 or RE17 for the creedmore. You could use RE17 in both, but you would likely have to use 48+grns in the 308 with the vlds jammed in the lands to get the pressure up. I do this with my 6br, everyones go to load for the br is about 30grns of varget under a 105vld touching the lands, mine is 34.5grns of RE17 with the 105s .030" in the lands, they get about 2775fps from 28-30" barrels, I get 3030fps from a 29" tube. You just gotta experiment.
