[QUOTE="bigedp51, post: 1211474, member: 28965"] What are you missing is if you buy quality brass then neck turning isn't required in a SAAMI chamber. What I was trying to get across was the poor quality of American brands of brass like the Remington brass that varied between .004 and .008 in neck thickness. If you go to AccurateShooter.com, F-Class shooters are using Lapua brass and do very little to the brass. Bottom line, why bother neck turning cases with .004 to .008 thickness variation and wasting your time trying to make bad brass better. And with a full length resized cartridge case the bullet is centered in the throat, while the rear of the case is being held by the bolt face. Meaning the clearance between the case and chamber gives the cartridge wiggle room to let the bullet self center with the bore. And it is the poorly made cases that warp and become banana shaped that cause alignment problems. So again, much of what benchrest shooters do with their custom rifles with tight neck chambers does not apply to poor folk with off the shelf factory rifles. [/QUOTE]
