[QUOTE="Lonewolf74, post: 2421657, member: 96274"] The outside neck diameter won’t change regardless of die used. The outside diameter of fired brass will be controlled by your chamber and brass spring back. The loaded round neck diameter is controlled by bullet diameter and brass neck thickness. Weather you size the neck to .001 or .005 under bullet diameter the brass will yield to your bullet during seating and loaded round diameter will be the same regardless. To keep clearance right as far as neck diameter goes you need to spec your chamber reamer for it. I took the measurement of the exact brass and bullet I intend to use and specified the neck diameter of my reamer to be .005 over this because I don’t want to neck turn and I feel a little more clearance is better on bigger cartridges. For the die being made if I go full length non bushing sizer die I would specify it to size the neck .002 under bullet diameter. If I go full length bushing die I would buy a few bushing from .002 to .005 under bullet diameter. I would also specify for the die to bump the shoulder .002 under the fired brass measurement and minimally size the body. There’s lots of approaches to take to reloading and all can produce great results. My approach is to keep it simple and use as few steps as I can to the finished product (bullet) because I believe every extra step taken has the chance to introduce variance in the finished product. So ultimately I strive to minimally full length size for all my rifles. [/QUOTE]
