[QUOTE="Bullet bumper, post: 737582, member: 17844"] I am pretty much with you on all that. One thing we should note is most BR loadings that are using bushings are also neck turning the cases . The bushing does not work all that well on unturned factory brass that may be variable in dimentions. If the brass is good then it's fine . However the Lee collet die will work on unturned brass and neck turned . We must not mix up what is suitable to competition and what suits the average home loader for hunting and casual target shooting. How well a case centers is also a function of how neatly it fits . If a case is over sized it will lay in the bottom of the chamber as new unfired factory ammo does in factory chambers . If the neck is a neat fit like a fitted neck turned case then it can't lay in the bottom of the chamber if the case neck is always a neat fit. So even if the base is reduced in diameter and a slight shoulder bump used the tight neck does most of the work keeping the bullet in the center of teh bore. That is why I use partial neck sizing in every bolt gun . I leave a short second shoulder that is never sized to do most of the centering work at the front and minimum body sizing at the rear and shoulder . [/QUOTE]
