I measured a sample of my formed PPU brass. No case was sufficiently over 2.224 max to be a concern. What I plan to do is load test a lot with this untrimmed brass. The idea is to neck size these cases then trim. From the shape of the cartridge using the FL die to necksize should not be a problem. This first small lot of rounds should give me an idea what comes next. I may try the scope later on. I have no interest in working up loads with potentially malfunctioning optics. That's crazy making. I'll share what's happening here as events unfold.
