Tailored for RCBS gold medal match series dies, these changeable, self-centering neck bushings give reloaders control over bullet grip by adjusting neck tension precisely. This reduces brass fatigue and case neck work hardening, improving both case life and accuracy. To optimize performance, consistent neck wall thickness in your brass is required. Choose the proper bushing by measuring the outside neck diameter of a loaded round and subtracting 0.002 - 0.003 inches or calculate by taking twice the neck wall thickness, adding the bullet diameter and subtracting 0.001 inches. RCBS recommends keeping multiple bushings within a two-size range of your ideal diameter.
