RE: Sizing Die Damaging Brass on Some Cases
Have you checked the die for possibly built up sizing lube that may have dried and hardened? I know that with my dies I check them for build up about every 2-300 loads. I have even found a piece of tumbling media that found its way in there. Anyways, it wouldnt hurt to just check and even take a qtip with some alcohol to clean it up. Maybe you have a different problem, but for it to only do what you are saying once in about 10 rounds sounds to me like something trapped in the die. Another thing that could be too, is media still in the brass from tumbling? Anyways, just some suggestions. Good luck in solving your problem.
