Has anyone had a problem with new 45 auto from brass from R-P spliting. I got 500ct form Midway five years ago. Just now loading them. After One load They have small splits. Ihave load this 100ct for the 500ct box four time now. how of that 100ct 22 have split.The load is 4.7 grs of WST 200swc not a hot load at all.My star brass does not do that. Iam out fo star brass now and can"t get more so far going back to ACP brass
