Would it be ok to neck turn unfired brass that has a neck runout of around .003-.005? The neck wall thickness varies by as much as .0015 on some cases. My concern is that the cutter will be removing too much brass because the neck isn't concentric. But maybe the neck turning pilot will keep things centered? I could fire form them before I neck turn but I'm running a bushing die and don't really want to have to run them over an expander ball again and induce runout thus having to fireform all 50 again before I can get really concentric ammo for load development. I appreciate your thoughts.
