RCBS Steel Neck Bushings are interchangeable to let the reloader select a bushing that gives precisely the right amount of tension on the bullet when using RCBS Gold Medal Match sizing dies. This .332″ diameter bushing is self-centering for proper alignment with case neck and features a precisely fitted design that reduces work hardening of the case neck brass, prolonging case life and helping to improve accuracy.
The bushing comes “in-the-white”—bare steel—so traditional case lubrication is required during the reloading process. For best results, the use of high-end brass with consistent neck thicknesses is recommended. This bushing is for use ONLY with RCBS Gold Medal sizing dies. RCBS recommends having neck bushings one to two sizes above and below your target diameter to allow for precise adjustment of neck tension to your specific brass and loading requirements.
