RCBS 0.332" Neck Bushing

RCBS gold medal match series dies benefit from these self-centering, swappable neck bushings that give reloaders the ability to control neck tension with surgical precision. This leads to extended case neck life and more accurate shooting due to reduced work hardening. To harness these advantages, reloaders must use premium, uniform brass. Determining the right bushing involves subtracting 0.002 - 0.003 inches from the neck diameter of a loaded cartridge or using a formula - double the neck wall thickness, add bullet diameter and subtract 0.001 inches. RCBS advises keeping nearby sizes on hand. Proudly made in the USA for superior quality and reliability
