Short Action Customs Neck Sizer Die Bushings have minimized neck runout in cartridge brass in nearly every die tested. After attempting to eliminate and reduce neck runout in sized brass using various commercially available neck bushings, SAC realized that every neck bushing has the same flaw, a straight, undersized hole when compared to the brass. Think about trying to push a thin walled straight tube into an undersized straight hole, how can we expect our brass necks to magically be free of runout. These bushings address the inherent flaws with this system with an internal bushing geometry designed to reduce neck runout while increasing loaded cartridge concentricity in the chamber.
