[QUOTE="Axl, post: 2785160, member: 90110"] Bumping your shoulder back .002" is an arbitrary figure. Your brass may not need to be bumped at all. I have a custom built 30 Nosler using ADG brass. After 3 firings the shoulder still doesn't need to be bumped. The kits mentioned above will only tell you the size of your brass- base to shoulder. What you need to know is the size of your brass in relationship to your chamber. You can do this without any of those gadgets. You just need to remove your firing pin and your plunger ejector. If the bolt will close without resistance on a fired case you don't bump the shoulder. If you have resistance, you adjust your size die a little at a time until the bolt closes easily. You can also determine where to seat your bullets in relationship to the lands using the stripped bolt. It is far more accurate than any of the tools sold to measure this. [/QUOTE]
