I was priming some R-P 9mm this morning and noticed a couple shells sitting crooked in the reloading block. Pulled them out to measure and they were about .010 +/- difference in length from one side of the case to another. Case mouth was cut crooked. All factory shot brass. Never had this with any other brass. I'll just either trim them down if there is room or toss them if they end up too short. Wondering if anyone else has had this?
