Product Description

These self-centering, changeable neck bushings let reloaders precisely set the amount of neck tension on the bullet when using RCBS bushing reloading dies. This reduces work hardening of the case neck brass, prolonging case life and increasing accuracy. These benefits are increased when using high-quality brass and turning necks for consistency.
 
Proper neck bushing size can be determined two ways. Please scroll down to see easy directions to confidently determine your required neck bushing size. RCBS suggests that reloaders get their determined size as well as the sizes .001 inches above and below their determined size. 
 
WITH A LOADED CARTRIDGE:

Step 1 – Measure the neck dimension with a caliper or micrometer.
Example: .295”

Step 2 – Subtract .002-.003” depending on desired neck tension.
Example: .295” - .002” = .293” Bushing Size

Step 3 – Add that size to your cart

This method allows approximately .001” of spring-back for proper neck tension.

 

WITH UNLOADED BRASS:

Step 1 – Measure neck thickness with Vernier ball micrometer or caliper and multiply it by 2 for a product.
Example: .015” x 2 = .030”.

Step 2 – Add your bullet diameter to the previous product, then subtract .001” for the proper neck bushing size.
Example: .264” + .030” = .294”, -.001” = .293” Bushing Size

Step 3 – Add that size to your cart

This method allows for .001” of spring-back for proper neck tension.
