[QUOTE="dwm, post: 403266, member: 1136"] This is intersting as I found a way to do this. :) What you need for this is a Redding body die, a Redding Small Base die, and a Redding type S neck sizer die. With these dies you can independently control the size of the base, how far the should is bumped back, and how far and to what diameter the neck is sized to. Kind of a pain to use separate dies, but yes, all dimensions can be controlled independently. I figured this out because my cases were not extracting when I opened the bolt. They would stick in the chamber and not want to come out. Yes, I could have turned the body die down so more of the body was sized, but I did not want to bump the shoulder back any further. The cases were sticking at the base, but the primer pockets are fine. This is where the Small Base die comes in. The Small Base die will not bump the shoulder, it only touches the base. So now I use the Small Base first, then the body die, and then the neck die. I am reducing the size of the base just enough so they don't stick in the chamber after firing, not very much much at all and bumping the shoulder 0.001" on annealled brass, then sizing the neck 3/4 of the length of the neck with a bushing that is giving me 0.002 neck tension, again measured on annealled brass. :rolleyes: [/QUOTE]
