So I had posted up a thread awhile ago about my necks splitting after only 3 or 4 firings. I changed my dies and am using a Redding type s full length sizing die with a .289 bushing and doing a .002 shoulder bump. I've been running Peterson brass lately and so far so good until today. I had one split on its 5th firing. I guess I'm at a loss as to why this keeps happening to me. It's happened on adg, Peterson, and norma. My fired necks measure .295 and I have .002 neck tension. I dont anneal my brass but I feel it should be lasting longer than 5 firings. Does anyone have any ideas? I do neck turn my brass but that's happened on non neck turned brass so I know that's not the problem.
