Enhance your reloading precision with RCBS Steel Neck Sizing Bushings!
RCBS Steel Neck Bushings are interchangeable to let the reloader select a bushing that provides precisely the right amount of tension on the bullet when using RCBS Gold Medal Match sizing dies. This critical component reduces work hardening of the case neck brass, prolonging case life and helping to improve accuracy.
Key Features:
- Self-centering for proper alignment with case neck.
- For best results, use high-end brass with consistent neck thicknesses.
- Bushings come "in-the-white" - bare steel - traditional case lubrication is required.
- For use ONLY with RCBS Gold Medal sizing dies.
- RCBS recommends having neck bushings one to two sizes above and below your target diameter.
RCBS Steel Neck Bushings are a small but essential component in loading extremely consistent-shooting ammo with your Gold Medal Match sizing dies.
Brownells Gun Tech™ Tip:
There are two ways to select the steel neck bushings you need:
- Measure the outside neck diameter of your loaded cartridge and subtract .002" to .003". This allows approximately .001" of brass to spring back for correct neck tension.
- Measure the neck wall thickness of your case, multiply by two, add the diameter of your bullet, and subtract .002" to .003".
