Thanks. I've notices a marked increase in accuracy between H4895(short stick) and Lever powder( small ball) in 30-30, wondered if peening is the problem. Ran some RD 311 170 PB butt first through the sizer. I'll shoot them and see if there is a difference. Bases have a sharp edge, not frilly like running them nose first. I shoot at a commercial range and have no way of recovering bullets.
