RCBS Exp-Decapping Unit Features The RCBS Exp-Decapping Unit is designed to pop the spent primer out of a case automatically as the case is inserted into the sizing die combining decapping and resizing into one smooth motion. This saves reloaders a separate step compared to using a standalone decapping die speeding up the overall reloading process. The pin is machined from hardened steel or another super hard metal specifically chosen to withstand the repeated stress of pushing out primers case after case. Because the unit is sized for the .221 Fireball cartridge it ensures proper fit and reliable function without the guesswork of using a generic decapping pin. RCBS manufactures decapping pins in a wide range of sizes to cover the most popular reloading calibers and this listing covers the dedicated .221 Fireball size. Reloaders who load this less common cartridge benefit from having a correctly sized replacement pin on hand since a worn or bent pin can slow down a high volume reloading session. The hardened construction is intended to extend the service life of the pin well beyond standard steel components. For .221 Fireball reloaders needing a dependable replacement or spare decapping pin the RCBS Exp-Decapping Unit is a simple purpose built solution.
