MEC Reloading E-Z Prime Features The MEC Reloading E-Z Prime automates the priming step on compatible 28 gauge single stage presses. Instead of manually placing each primer the unit feeds primers automatically as the press cycles reducing fumbling and wasted motion at the bench. This conversion keeps the loader s hands free to manage powder wads and shot charges rather than individual primers. The result is a faster more consistent loading session with fewer interruptions. The attachment is built from a combination of plastic and steel components finished in black and silver for durability under repeated use. It includes a tray assembly a bracket assembly and an actuator chain along with complete installation instructions for a straightforward setup. Designed specifically to fit MEC Model 600 and Model 700 single stage loaders it is a dedicated upgrade rather than a universal part. The MEC Reloading E-Z Prime is a practical addition for any reloader running high volumes of 28 gauge shotshells.
