RC BUSHING DIAMETER - 0.364

The RC Bushing Diameter - 0.364 is an essential reloading component designed for precision ammunition handloaders and competitive shooters who demand tight tolerances and consistent cartridge dimensions. This RCBS bushing serves as a critical sizing die insert that controls bullet seating depth and case neck concentricity during the reloading process. Whether you're loading match-grade rifle rounds or high-volume pistol ammunition, this bushing ensures your finished cartridges meet exact specifications for reliable firearm function and superior accuracy.

Engineered by RCBS, a trusted name in reloading equipment since 1954, the 0.364-inch diameter bushing works within standard reloading press dies to precisely control case neck expansion and bullet alignment. The hardened steel construction resists wear during repeated use, maintaining dimensional accuracy across thousands of reload cycles. By selecting the correct bushing diameter for your specific caliber and bullet combination, you achieve superior case-to-bullet fit, which translates directly to improved velocity consistency, tighter shot groups, and reduced vertical stringing downrange.

This bushing is ideal for handloaders working with cartridges like .308 Winchester, .223 Remington, and similar centerfire rifle rounds where neck tension control is paramount. The compact 1.5-inch length and lightweight 0.2-pound design make it easy to swap between bushings when loading multiple calibers on a single press. Installation is straightforward—simply insert the bushing into your RCBS die assembly and adjust your press for proper seating depth. Serious reloaders building ammunition for precision rifles, competition shooting, or hunting applications will benefit from the consistency and repeatability this component delivers.
