Yeah, I completely forgot to mention I was having case head separation on the second firing...also with light loads. I think it is something with the neck and shoulder area itself. Maybe I just got a batch that was over annealed or something. My cases are coming out from an expander mandrel extremely rough. I have to actually dip my necks in some imperial wax to limit this, but even then some are coming out extremely stretched, looking more like a sausage than a shoulder.... I can run other brands through my expander mandrel with a light coating of one shot, so it has to something with the brass itself. I just wish Peterson would have made it right, especially after saying they would. I'll give them the benefit of the doubt in today's situation, maybe my emails got overlooked or lost. It just sucks to have to toss so much brass and start from scratch with starline.
