Achieve Precision with RCBS Steel Neck Sizing Bushings
RCBS Steel Neck Bushings are essential for reloaders seeking the perfect amount of tension on the bullet when using RCBS Gold Medal Match sizing dies. These bushings are designed to be interchangeable, allowing you to select the optimal size for your needs.
Key Features:
- Reduces work hardening of case neck brass, extending case life and enhancing accuracy.
- Self-centering design ensures proper alignment with the case neck.
- Recommended use of high-end brass with consistent neck thicknesses for best results.
- Comes "in-the-white" - bare steel, requiring traditional case lubrication.
- For use ONLY with RCBS Gold Medal sizing dies.
RCBS advises having neck bushings one to two sizes above and below your target diameter to ensure optimal performance. The Steel Neck Bushings are a small but critical component in loading ammunition that shoots with exceptional consistency.
Brownells Gun Tech™ Tip:
There are two effective methods to select the steel neck bushings you need:
- Measure the outside neck diameter of your loaded cartridge and subtract .002" to .003". This allows for approximately .001" of brass to spring back for correct neck tension.
- Alternatively, measure the neck wall thickness of your case, multiply by two, add the diameter of your bullet, and subtract .002" to .003".
