[QUOTE="Arkansasdad, post: 1913790, member: 76766"] Start checking the TIR at the base of the cartridge as close to the chuck as possible and move forward in small increments, you may find it is the chuck giving you a secondary axis. Brass base will not be totally perpendicular to the body, remember we are dealing with an annulus and it can never be an exact plane. All arrows, pipes, gun barrels, or anything hollow cannot be truly straight. Bullet center may be more tolerant of axial run-out since the center of gravity is displaced less than the outer dimension reads. [/QUOTE]
