RCBS Expander Decapping Unit Features The RCBS Expander Decapping Unit is machined from hardened steel to withstand the repeated mechanical stress of popping spent primers out of case after case during high volume reloading. As each case is inserted into the sizing die the decapping pin pushes the spent primer free clearing the primer pocket for a fresh primer during the next step of the reloading process. This .270 taper specific unit is sized to match the case geometry of that caliber ensuring proper alignment and consistent decapping with every stroke. Reliable decapping is a foundational step in quality reloading since a bent or worn pin can damage primer pockets or fail to clear the spent primer entirely. RCBS produces decapping pins and assemblies in a range of sizes to cover the most popular cartridge calibers and this unit is a direct fit replacement or spare for .270 taper die setups. Keeping a spare decapping unit on hand is a smart practice for active reloaders since this is one of the more wear prone components in a sizing die assembly. Replacing a worn pin restores smooth reliable decapping without the need to purchase an entire new die set. For reloaders who depend on consistent case prep the RCBS Expander Decapping Unit offers a simple affordable way to keep a .270 die running at full performance.
