RCBS
Decapping Unit Only .310

These RCBS factory replacement decapping units are the same ones we ship with our products — so you can rest assured they will work.

These replacement decapping units feature an expander rod, expander ball, and decapping pin. They are used in sizing dies to de-prime the case and expand the case neck in bottleneck cartridges. It is always a good idea to keep an extra decapping unit on-hand so you can ensure your reloading sessions do not get interrupted if you ever damage them during use.
