[QUOTE="406pat, post: 321734, member: 13575"] Given that your shorter brass is chambering easier, I think you found your problem. You'll want to trim your brass [U]after[/U] sizing. Full length size that twice fired brass that's shorter right now and then measure it. I bet you'll be surprised to find it's longer than it was. The reason is that when you fire, the brass stretches to fill the chamber neck. The chamber neck is larger than the space allowed for in the sizing die so when you size the brass it gets squeezed back down to tollerance. That displaced brass has to go somewhere when it's squeezed back to size and the easiest place for it to go is to extend the lenght of the neck. I would say give trimming after sizing a shot before you start tearing dies apart. Unless, of course, curiosity has the best of ya and you just feel like tearing 'em up!:) [/QUOTE]
