RC BUSHING DIAMETER - 0.251

The RCBS RC Bushing Diameter 0.251 (SKU RC81566) is a precision reloading component designed for shooters who prioritize consistency in case neck sizing. This bushing plays a vital role in the RCBS bushing-style sizing die system, controlling the inside diameter of the cartridge case neck to ensure repeatable ammunition dimensions and reliable chambering in firearms.

With a diameter of 0.251 inches, this bushing is tailored for specific cartridge applications where precision neck sizing is crucial. Bushing-style sizing dies allow reloaders to adjust neck tension independently of shoulder and body sizing, leading to tighter load consistency and improved shot-to-shot velocity uniformity. This level of control is particularly beneficial for handloaders focused on match-grade ammunition and competitive shooting.

Reloaders working with precision bolt-action rifles or preparing ammunition for benchrest or long-range competition will find the ability to control neck diameter with a dedicated bushing invaluable. RCBS bushings are manufactured to exacting tolerances and are interchangeable across the brand's bushing die platform, making this component a practical addition to any serious reloader's toolkit.
