[QUOTE="J E Custom, post: 1630737, member: 2736"] Full length dies for belted cases address the shoulder clearance first and body dimensions after the shoulder has started moving,so What I do is back off on the full size die and test one case as I tighten the die for case length from shoulder to case head. I will unscrew the expander ball if that is the type of die I am using and start sizing a fired case, testing it as I go in the chamber or with a case gauge to get the minimum sizing/ shoulder bump needed. Once I get the case partially sized I will lock down the die and install the expander ball and start sizing all fired brass. I minimize the neck sizing during this process and once the case body is where I want it I do the necks. For accuracy, I want to feel a small resistance when closing the bolt on a shouldered case. (No bolt slack) if it is a belted case and i am using it as such, I like it with around .0005 head space. if it is for dangerous game, I go ahead and full size belted cases. If I buy some new belted cases, I check them for head space because the belt can be thicker on different brands and I want minimum head space for the first firing to prevent excessive case stretch. Just the way I like to size belted cases J E CUSTOM [/QUOTE]
