MEC 812012 Sizemaster Single-Stage 12 Gauge Shotshell Reloader

The MEC Sizemaster single-stage shotshell reloader is a purpose-built 12 Gauge reloading press designed for the shooter who wants to turn fired shotgun hulls into fresh, reliable target and field loads at the home reloading bench. Built around a single resizing station, the Sizemaster delivers a straightforward, dependable platform with the rugged construction MEC is known for.

The resizing station handles both brass and steel heads in either high or low base configurations, and the press is adjustable for 3-inch shells, giving reloaders flexibility across a wide range of 12 Gauge hulls. An E-Z Prime auto primer feed streamlines the priming step, and the multi-size threading accepts a variety of shot and powder bushings. With a typical output of 4 to 6 boxes per hour, the Sizemaster is well suited to the shotgunner who reloads regularly for sport, clays, or field use.

This steel-constructed, 1-hole press ships ready to run, including 3 bushings (sizes 29, 30, and 32) and 1 charge bar. Whether you are just getting into shotshell reloading or looking to replace an older single-stage unit, the MEC Sizemaster offers a proven, user-friendly design backed by one of the most recognized names in shotshell reloading equipment.
