For use with RCBS gold medal match series dies. Works in both the full length and neck sizing styles.

Neck bushing size (RCBS instructions):

• Proper neck bushing size can be determined two ways.
• Measure the outside neck diameter of your loaded cartridge, subtract .002″ to .003″. This allows approximately .001″ of brass spring back for correct neck tension.
• The other is to measure the neck wall thickness of your case, multiply by two, add the diameter of your bullet and subtract .001″.
• RCBS suggests that you have neck bushings one to two sizes above and below your target diameter.

   

Notes:

• Tungsten disulfide has an extremely low coefficient of friction (0.03, titanium nitride is 0.6)
• Redding, Wilson and Hornady bushings may also be used in RCBS Gold Medal bushing dies
