ZOEKIM 12 Pack Decapping Pins
For reloaders seeking a reliable and cost-effective replacement for their RCBS decapping pins, the ZOEKIM 12-pack offers a compelling solution that directly addresses a common point of failure in the resizing process.
Pros
The primary advantage of these pins is their redesigned headed construction. This design provides a significantly larger surface area for the die to grip, which virtually eliminates the frustrating issue of pins slipping down during use. The heat-treated hardened steel provides excellent durability against standard brass, and the generous 12-piece pack means you have ample spares on hand for years of reloading.
Cons
The machining on some pins can show minor tooling marks, though this does not impact function. As noted by the manufacturer, you should anticipate slight variances in dimensions due to manual measurement, so a perfect match to every OEM pin’s exact length or head diameter is not guaranteed, though they function correctly in standard dies.
This pack delivers exceptional value by solving the slippage problem with its smart design, making it a highly practical upgrade over basic straight pins and a trustworthy alternative to more expensive ed options.
