RCBS Full Length Die Set - Group D - Bottleneck Rifle Cartridge 5.6x50 Rimmed

The RCBS Full Length Die Set Group D for Bottleneck Rifle Cartridge 5.6x50 Rimmed (MPN 26301) is a precision reloading solution designed for shooters who demand exact case preparation and consistent ammunition assembly. This two-die set combines a full-length sizer die with integrated expander-decapping unit and a seater die with bullet seater plug, delivering SAAMI minimum cartridge dimensions and reliable performance across high-volume reloading operations.

The full-length sizer die resizes the case body to specification while decapping spent primers and expanding the neck to accept incoming bullets. Precision venting prevents case damage from trapped air and excess lubricant—a critical feature for maintaining case longevity during repeated reloading cycles. Headspace is held to minimum tolerances, ensuring consistent cartridge dimensions and preventing unintended case body elongation that degrades accuracy over time. The seater die positions each bullet to exact depth, essential for uniform velocities and ballistic consistency shot-to-shot.

This die set serves precision rifle reloaders, competitive shooters, and handloaders working with 5.6x50 Rimmed bottleneck rifle cartridges. The Group D classification indicates compatibility with RCBS's standardized press mounting system, allowing rapid die changes and integration into established reloading workflows. Shooters operating in high-volume environments benefit from the die set's ability to produce ammunition meeting tight tolerances batch after batch, supporting accuracy demands in target shooting, load development, and field applications where consistency matters.
