Re: Please help w/ Redding body die and shoulder bump
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Srzbiznz</div><div class="ubbcode-body">Okay so I tried bumping the shoulder back from an unfired case and the case slid into the die without much resistance and the most shoulder bump I could get was at 1.6210 before the die bottomed out on the shell holder. I was aiming for 1.6210 as my shoulder length because my fired cases came out of the chamber at 1.6240. Does that sound about right or am I doing something wrong? </div></div>
For bolt guns, .001"-.002" of shoulder setback is fine. You really just want the sized case to chamber with the slightest amount of resistent--a snugness if you will.
I can go 2-4 cycles without having to worry about shoulder bumps for my various calibers, so I can get away with neck sizing only.
For gas guns, or maybe critical competitions, where you you need a bit more wiggle room and have to have a round chamber, .002"-.004" should be fine.
We're really not talking about a significant amount of sizing, to be sure.
The less you size, the less case stretching you'll have.
