[QUOTE="bigngreen, post: 960019, member: 13632"] I'll see if I can remember all the numbers, my brass last so long I only prep 50 cases per barrel. I found that it's just easier to run Norma brass and it's so consistent that even just pulling .001 of the neck would completely clean it up, Win brass is frankly not worth the effort to shoot, Rem brass is OK needs turned and handles the most pressure of the three but you will see groups snug up just from changing to Norma so any more that's all I would suggest running. There is just not a reason to make them overly tight, .003 neck clearance is good but I think .004 is better for accuracy and just over all ease of use, pressures stay more even and everything is just more harmonious IMO. Norma brass loaded runs .308 on the neck, Rem runs .310, my tight neck reamer is .310. My next reamer will be .312 for no turn on Norma and a light turn on Rem but no real intention of running it. For a shoot every thing out there a .314ish is what you'd want. Definitely use bushing dies like the Redding S and annealing is a must! [/QUOTE]
