NECK SIZING BUSHINGS

UNIVERSAL OUTSIDE DIMENSIONS OF .500″ DIAMETER BY .375″ HEIGHT, THESE BUSHINGS CAN BE USED IN MOST RESIZING DIES.  THESE WILL NOT WORK WITH SAC MODULAR SIZING DIES

Our neck resizing bushings have minimized neck runout in cartridge brass in nearly every die we have used them in. After attempting to eliminate and reduce neck runout in our sized brass using various commercially available neck bushings, we 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. Our new bushings address the inherent flaws with this system with all new internal bushing geometry designed to reduce neck runout while increasing loaded cartridge concentricity in the chamber.

Made from 17-4  stainless steel, then processed with the same black nitriding as our Precision Resizing Dies. Our neck bushings have an incredibly smooth inside finish paired with an extremely slick external finish from nitriding and polishing.
