[QUOTE="25WSM, post: 2071115, member: 38048"] Neck thickness is totally dependent on chamber neck diameter. There is no one perfect neck thickness in general. If you have .003 to .004 clearance it will be good. More don't really hurt accuracy but will work the necks more during sizing and need annealed more often. In the 6ppc necks at .008 thick are the norm. And these brass last for a dozen shots minimum. So anything under .012 and start over is just wrong. If your brass already have .003 to .004 clearance then you only need to do a 75% clean up on the necks. Don't skimp on the neck turning equipment. You won't be happy. Get a 21st century, KandM or Sinclair. Clean up cuts go real fast and are easy to get nice. Do make sure you cut into the shoulder slightly also as this helps with the donut forming in the junction. I neck turn almost all my brass to at least a clean up stage. And all my BR guns need turned brass. Biggest difference I ever seen was 300wsm winchester brass that I did a 75% cleanup on and reduced groups by more than half. These brass had sides that were more that .002 bigger on one side. Have fun with it. Shep [/QUOTE]
