[QUOTE="Moman, post: 362341, member: 10494"] JE, with your permission, I would like to delve a little more into neck turning and how it may effect runout/concentricity. I think what I'm after will stay on topic. How many of the posters up to this point neck turn their cases? I ask because in the past I have settled for .001 neck wall variance and have been happy with that number. I have had trouble with this last lot of brass in that neck wall variance is anywhere from .001 to .005. The majority of the cases are .003. Runout on these loads it gynormous. How much of a difference would it make if I were to neck turn these cases to .001 variance or less? How much would this help with runout? [/QUOTE]
