RC BUSHING DIAMETER - 0.312

The RC BUSHING DIAMETER - 0.312 is an essential component for precision handloaders looking to achieve consistent neck tension on their rifle cartridges. Designed for use with RCBS Gold Medal Match Series dies, this bushing allows for incremental control over the outside diameter of the case neck during the sizing process. By selecting the specific 0.312-inch diameter, reloaders can minimize brass fatigue and improve accuracy by ensuring a uniform grip on the projectile. This tool is a staple for competitive shooters and long-range enthusiasts who demand exacting specifications from their custom-tailored ammunition.

Constructed from high-grade steel, the RC BUSHING DIAMETER - 0.312 is precision-machined and heat-treated to maintain its internal dimensions over thousands of reloading cycles. The internal surface is polished to reduce friction, which prevents galling and ensures smooth case entry and exit without the need for excessive lubrication. Because this bushing is interchangeable within the die body, it provides the versatility to adjust for different brass brands or wall thicknesses without purchasing entire new die sets. This level of technical control over neck diameter is critical for maintaining consistent pressures and velocities across every string of fire.

This RC BUSHING DIAMETER - 0.312 is compatible with RCBS Gold Medal Match, Neck, and Seater dies, as well as several other industry-standard bushing-style dies. To ensure the best performance, users should measure the outside diameter of a loaded round's neck and subtract approximately 0.001 to 0.002 inches to determine the correct bushing size for their specific chamber. Installation is straightforward, as the bushing drops into the top of the die and is secured by a threaded cap, allowing for quick adjustments in the field or at the bench. Serious reloaders will benefit from having a range of these bushings to account for variations in brass lots and chamber dimensions.
