Rcbs Full Length Die 7.62x39-.308/31

The RCBS Full Length Die 7.62x39-.308/31 is a two-die reloading set engineered for precision ammunition assembly in bottleneck cartridges used in semi-automatic, pump, and lever-action rifles. This set includes a Small Base Sizer with integrated Expander-Decapping Unit and a Regular Seater Die with built-in roll crimper, providing a complete sizing and seating solution for shooters who demand tight chamber performance and consistent ammunition specifications.

The Small Base Sizer resizes cases below SAAMI minimums, reducing both shoulder and body dimensions by a few thousandths of an inch to ensure reliable feeding in tight-chambered actions. Simultaneous de-priming removes spent primers cleanly in a single stroke. The seating die's integrated roll crimper applies uniform bullet tension during seating, eliminating the need for a separate crimping step—though the crimp can be disabled by simply unscrewing the crimper plug, allowing shooters to seat bullets without crimping when preferred for their specific applications.

This die set is purpose-built for the 7.62x39 cartridge used in modern sporting rifles and military-pattern semi-automatic platforms. Reloaders working with tight-tolerance chamber specifications—whether for increased accuracy, enhanced feeding reliability, or specialized ammunition testing—benefit from the Small Base Sizer's ability to reduce case dimensions to match exacting requirements. The two-die configuration streamlines the reloading process while maintaining the precision that serious rifle shooters expect from RCBS equipment.
