I tried 60, 70, 80, 90 and 100 gr in 2Fg. The 70 and 80 seemed about tied, though that was with .535 RB and .018" patch, which is quite tight to load. This time I tried .530 RB which loaded better, spent patches seem OK, no cutting at lands. Have tried some .54 Minie, but the ones I have are not real consistent in weight, and skirts visibly vary in thickness. Groups a little more open and a little lower, but a snap to load.
Where might I find some of the bullets you mentioned?
