RCBS Exp-Decapping Unit 6.5mm X-small Pin (.057 Pin)

The RCBS Expelling Decapping Unit with 6.5mm X-Small Pin (.057 Pin) is a precision component designed for shooters and reloaders who demand reliable primer removal from fired brass. This hardened steel decapping pin is engineered to consistently eject spent primers as cases pass through the decapping die, making it essential maintenance equipment for anyone managing their own ammunition production or case preparation workflow.

The .057-inch pin diameter is specifically matched to 6.5mm cartridge cases and smaller calibers within that family, ensuring proper primer pocket clearance and preventing case damage during the decapping cycle. RCBS manufactures these pins from hardened steel or comparable super-hard alloys that withstand repeated striking forces without dulling or breaking prematurely. The compact dimensions (2.5 x 0.25 x 7.5 inches) and minimal weight (0.03 lbs) mean the pin integrates seamlessly into standard RCBS die assemblies without adding bulk or requiring tool modifications.

This component is essential for reloaders preparing large quantities of 6.5mm Creedmoor, 6.5mm PRC, or similar cartridges for precision rifle applications, match training, or supply chain rebuilding. Precision rifle enthusiasts and volume loaders rely on RCBS decapping units to maintain consistent case condition before resizing and repriming. Having the correct pin size prevents the frustration of stuck primers or compromised case integrity that can occur when using oversized pins.

RCBS decapping pins come in multiple sizes to accommodate the full spectrum of popular rifle and pistol calibers. Ordering the correct pin size for your specific cartridge is critical—the X-Small designation indicates this pin is calibrated for the 6.5mm family and smaller applications, not universal for all rifle rounds. Verify your case caliber and primer pocket diameter before purchasing to ensure proper fit and function.
