Which 80's did you shoot? I'm going to resume LD on a Varget/80gr MK load this spring, and I'm near 2 grs hotter than my go to 73gr load already. Digging the BC's, and the faster the better, but at the expense of brass life... I may end up pulling it back into the slow lane and riding the wave gently to get more use out of my cases. Are you constantly doing LD in new cases?
