[QUOTE="BountyHunter, post: 961473, member: 12"] Ok, you have 5 different chambers of 5 different lengths to shoulder etc and wonder why there are issues? IF you want to try and shoot the same brass in all five guns you are going to have to size ALL brass and bump shoulders to the smallest chamber. Brass life will not be good. You are going to have to start with virgin brass again in each gun, and fire 4-5 cases at least 3x and measure to find the smallest chamber at the base, shoulder and shortest at the shoulder. Adjust the one die set to compensate for both and go for it. Otherwise couple choices. 1. Segregate all brass by gun. I have 3 WSMs now (down from 5) and do that. 2. Each gun has its own set of dies adjusted to that gun with shellholder in the die box. Shellholders will vary in height even though not supposed to. Multiple die sets and some minor cost, but simple fix that is 100% every time! 3. It is possible to load multiple guns with one set of dies using Otto die shims to go under the lock ring of the die adjusted to the shortest case at the shoulder and use the corresponding rings to raise the die up for the longer cases.
