An expander rod, expander ball, and decapping pin are included in these replacement decapping units.
In bottleneck cartridges, they're utilized in sizing dies to de-prime the case and extend the case neck.
It's always a good idea to have an additional decapping unit on hand so that your reloading sessions aren't disrupted if you damage one while using it.
