Or get a redding body die and a Lee collet die.
So that it feeds into the chamber and, even more importantly, extracts back out easily.
You're not going to get benchrest accuracy (groups in the 1's) out of a RPR or out of most any "precision" rifle out there so why waste your time and compromise reliable feeding and extraction by using benchrest-only resizing?
This isn't that complicated.
Get a Redding Type S die with a small assortment of neck size bushings. Set the die to push the shoulder back .001 - .002, use the bushings to tune neck tension, and let the die body resize the case body.
If you don't use a sizing button in conjunction with the type S die, you'll need to turn the neck OD to end up with even wall thickness inside the neck.
Either way.. neck sizing only sucks. Even the LR benchrest guys FL size now days.
