[QUOTE="Bravo 4, post: 1182322, member: 8873"] I don't know. Maybe the brass cases are experiencing a little spring back and the nickel plated cases don't. I had the same thing happen to me. I was necking up .300 RUM brass to .338 and pushing the shoulder back to make .338 RUM. I have two sets of .338 RUM dies and neither would push the shoulder back enough to get an easy bolt close, it was pretty stout to close if at all. I made a brass shim from an old piece of brass (that was .016" I believe) and put it under a piece of brass in my shell holder. After running it through my FL sizing die the brass chambers perfectly, and I've only had to do it that initial time. [/QUOTE]
