Thread: Case Neck runout with redding type s bushing die

I wouldn't bother with neck turning. It's just a pain in the butt for hunting rifles which usually have about .006"- .008" neck clearance. Also, I doubt if you'll see much of an improvement in accuracy between .001"- .005" run out. If you do it will be minimal and make no difference at most hunting distances. Different for bench rest and long distance rifles where every fraction of accuracy is desirable.

With the Redding bushing dies you should be backing off the adjustment stem about a third of a turn so that the bushing has some float
