MEC E-Z Prime Automatic Primer Feed

The MEC E-Z Prime Automatic Primer Feed is a precision reloading accessory designed for shooters and ammunition manufacturers who demand efficiency and consistency at the loading bench. Built by Mayville Engineering Company—a manufacturer with decades of reloading equipment expertise—this automatic primer feed system eliminates the tedious manual priming process that slows production on high-volume reloading operations.

The automatic primer feed mechanism uses gravity-fed and mechanical indexing to deliver primers consistently and safely to each loading station without interruption or double-feeding. This design reduces operator fatigue during extended reloading sessions while maintaining the precision tolerances required for reliable ignition across different primer sizes and types.

This accessory benefits reloaders working with high-capacity primer trays and those processing rifle or pistol ammunition. The compact footprint mounts directly onto compatible MEC progressive press platforms without requiring additional bench space or complex modifications, making it an essential tool for efficient reloading.
