I use the Redding shellholder kits that allow the die to touch the shellholder while still allowing control of the shoulder bump, or lack of it if that is what you want. As the one poster noted, a neck sized case will be hard to chamber after a few firings, then start with the 0.010 thicker shellholder. If that doesn't allow easy chambering, use the 0.008, and so forth till the crush fit almost, or completely disappears. Write in your die box which shellholder to use so you don't forget.
You are then bumping the shoulder a maximum of 0.002" which I can live with for hunting ammo.
