sizing dies.

Re: sizing dies.

Well, I use a lot of stuff. Since you have a seater, I'd suggest a Forster FL sizer or a body/shoulder bump die and a Lee Collet Neck Sizer.

I'm sure a lot of folks use the X die for bolt guns. The X die doesn't stop stretch, it only pushes the excess length back inside the shoulder. But, if you only neck size, or FL size right, you will get very little case stretch anyway so trimming wouldn't be much of a problem.
