[QUOTE="Mike Matteson, post: 2448003, member: 101791"] A great many years ago, I necked sized my brass. I was mainly was using 308 Norma Mag. So I FL size 300WM brass to conformed to that chamber. I was having problem with the case stretch at the belt using a FL sizing die for my 308NM. So I got a 300WM neck sizing die. People probable wondering why? Neck length are different and case to shoulder is different too. It only sized about half of the neck and didn't bump the shoulder. Stop the case stretch problem. By only bumping the shoulder by a couple of thousand is better. By having less movement on the brass at the shoulder. That's cut down the case stretch too. Yes I have a lot die's that I won't be using now. Having to purchase more bushing die's too. Back to "I wish I knew them, what I know now. I would have a few dollar more in my pockets. The bumping came about for me by reading here and learning. Oh pocket be deep, so I can dig deep. [/QUOTE]
