Rcbs Rockchucker Supreme Auto - Prime

The RCBS Rockchucker Supreme Auto Prime is a fully automated priming tool engineered for serious reloaders who demand precision and efficiency at the bench. This priming system eliminates manual hand-priming fatigue while maintaining the tight tolerances critical to consistent ammunition performance. Built for both pistol and rifle cartridge applications, the Rockchucker Supreme Auto Prime streamlines the priming process—one of the most repetitive yet essential steps in the reloading workflow.

The automatic priming mechanism uses RCBS's proven ram-driven design to seat primers with consistent depth and force, reducing flyer rounds caused by primer seating variation. The compact footprint (14.95 inches tall, 3.3 inches wide) allows integration into tight bench setups alongside your progressive or single-stage press. A spring-activated primer feed system accepts standard large and small rifle or pistol primers, while tactile and audible feedback confirms proper primer seating. The robust aluminum construction and replaceable primer components ensure long-term reliability through thousands of reloading cycles.

Reloaders working high-volume magnum rifle loads or competition pistol ammunition benefit most from the Rockchucker Supreme Auto Prime's speed and repeatability. Whether you're prepping brass for precision long-range shooting or stocking competition ammunition, this tool reduces hand strain and operator variability. The unit works independently or as a press-mounted accessory, making it adaptable to existing setup configurations. At 1.2 lbs, it integrates seamlessly into modular reloading stations without requiring permanent bench modification.
