The RCBS Expander Decapping Unit .30 Caliber (09812) fits reloaders who have bent, worn, or broken expander rods or pins in their .30 caliber RCBS sizing dies and want to restore full function quickly.
Swapping to this complete assembly can cure neck-tension inconsistencies and erratic depriming caused by damaged or out-of-spec original parts.
Keeping a spare .30 expander-decapping unit on the bench helps prevent a damaged rod or pin from shutting down your loading session when working with common .30/7.62mm cartridges.
