RC BUSHING DIAMETER - 0.248

The RC Bushing Diameter - 0.248 is a precision reloading component manufactured by RCBS, one of the industry's most trusted names in ammunition and cartridge preparation equipment. This bushing serves as a critical sizing die accessory for handloaders who demand repeatable, match-grade accuracy in rifle and pistol cartridges. Whether you're a competition shooter chasing sub-minute-of-angle groups or a serious hunter preparing ammunition for ethical, one-shot kills, proper bushing selection directly impacts cartridge concentricity and neck tension—two non-negotiable factors in consistent ballistics.

The 0.248-inch diameter bushing is engineered to work within RCBS's modular reloading press system, specifically designed for neck-sizing operations that control bullet runout and reduce dimensional variance from round to round. Bushings of this specification are commonly used in bottleneck rifle cartridges where precision neck control is paramount. The hardened steel construction ensures durability across thousands of reloading cycles without deformation, maintaining consistent sizing geometry that directly translates to tighter shot groups and improved velocity uniformity. Proper bushing fit within the die body eliminates radial play, a fundamental requirement for achieving the concentricity tolerances demanded by modern precision handloading standards.

This bushing is ideal for reloaders preparing ammunition for bolt-action rifles, precision rifle matches, or benchrest competition where every tenth of a grain of powder and every thousandth of an inch matters. Law enforcement armorers and military support personnel who maintain precision rifle programs will recognize the value of RCBS bushings in standardizing ammunition preparation across multiple shooting platforms. Installation is straightforward: the bushing seats directly into compatible RCBS sizing dies. Verify your die model and current bushing diameter before ordering to ensure seamless integration into your existing reloading setup. Proper maintenance—occasional cleaning and light lubrication—will extend service life indefinitely.
