The RCBS Expander Decapping Unit in .223 Remington/5.56 NATO (RCBS part no. 09802) pairs an expander rod and ball with a decapping pin, and it is used inside a sizing die to knock the spent primer out of the case while expanding the neck of a bottleneck .223 Remington/5.56 NATO case in the same pass. Keeping a spare unit on hand is common for high-volume reloaders since the decapping pin is a wear part that eventually needs replacing.
