[QUOTE="MagnumManiac, post: 1119631, member: 10755"] Are you turning your necks to fit the chamber, or just to get them uniform? Even my match grade chambers don't get neck turned brass, only my tight neck chambers get it, and even then I try to find a brand that only requires the absolute minimum cut to clean up and fit. If you have a factory rifle and chamber, you may be introducing too much neck clearance by turning necks. .006" is absolute maximum for good accuracy when talking neck clearance, .003" is minimum for proper function. If it has a factory chamber, I would measure fired case necks and determine how much clearance is present before I cut any necks. Too much neck clearance is worse than not turning at all.
