RC BUSHING DIAMETER - 0.365

The RCBS RC Bushing Diameter 0.365 (part number 81680) is a precision reloading component designed for shooters who require exact case neck control during the ammunition loading process. This bushing is essential for the RCBS bushing-style sizing die system, favored by handloaders for achieving superior concentricity and consistent bullet seating depth.

With a diameter of 0.365 inches, this bushing effectively resizes fired cases to precise neck dimensions, reducing runout and ensuring smooth chambering while maintaining uniform neck tension on the seated bullet. The design allows the bushing to float on a hardened steel mandrel, enabling targeted sizing of the case neck without affecting the entire case body, which helps preserve case-wall consistency and extend case life.

This component is ideal for precision rifle and handgun reloaders who prioritize accuracy and consistency, whether for match-grade ammunition in competitions, hunting, or precision training. The 0.365 bushing effectively addresses neck runout, a key factor in vertical dispersion at distance, making it a valuable tool for serious handloaders.
