Designed to fit the RCBS gold medal match series, these neck bushings self-align and allow for precision control of bullet grip by adjusting neck tension. This minimizes case neck work hardening, promoting better accuracy and longer brass lifespan. Brass uniformity is key to effectiveness, so only high-end brass with consistent wall thickness should be used. Calculate your ideal bushing size by subtracting 0.002 - 0.003 inches from the loaded cartridge's neck diameter or apply the neck wall thickness formula. RCBS recommends reloaders maintain a range of bushing sizes around the target value.
