[QUOTE="AZShooter, post: 844077, member: 5219"] I think most would agree neck turning can help make neck tension consistent with brass that has uneven neck wall thicknesses. 284 win brass comes to mind. As for what wall thickness the cartridge ends up with depends on the chamber reamer's neck diameter. I prefer to have .003" to .004" clearance per side for bullet release. I have a 30 BR reamer that is working with .001" clearance per side. IMO a tight release clearance requires diligence and attention to detail. Carbon must be removed with steel wool after every shot. I have also discovered after several firings/sizings that the necks must be turned again as they thicken slightly. If one decides to turn necks on a factory hunting rifle that already has more than ample neck release clearance the neck tension consistency might improve accuracy but the necks could split early in the life of the case. I know I am guilty of doing exactly that with my first attempts at neck turning for a large case neck clearanced 284 win. Skim turning and removing approximately 80% of the brass from the neck is the best approach for no turn chambers. Just realize the necks might be the first part of the case to fail. [/QUOTE]
