Factory replacement parts for your RCBS dies. Using factory replacement parts ensures a perfect fit and proper function in your reloading dies. 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. FeaturesFactory Replacement PartPrecision Machined to ensure concentricityExpander Rod, Expander Ball and Decapping Pin
