A shooter @ Camp Perry in the late 50's or early 60's wrote an article which was published in the NRA's Reloading Manual of that era, regarding runout and effect on accuracy. I don't have access to those books at the moment but if memory serves, he determined that .002" runout was the magical dividing line. He also determined that over .0045" runout it didn't get any worse for accuracy. That's part of the reason I don't turn necks (which is what I hate to do most about reloading!) and use brass that has less than .0015" uniformity in the necks.
