MEC Sizemaster 20 Gauge Shotshell Reloading Press Single Stage Cast Iron

The MEC Sizemaster is a single-stage 20 gauge shotshell reloading press built for the shotgunner who reloads at home. Manufactured by MEC on a heavy cast iron frame, the Sizemaster is a proven, no-nonsense entry-level shotshell press designed for straightforward operation and decades of dependable service on the reloading bench.

This model is factory set for 2-3/4" shells and adjustable for 3" magnum shells, giving reloaders coverage across the most common 20 gauge hull lengths. The integrated sizing station handles both high and low brass heads and resizes every base back to factory specification, while the automatic primer feed keeps the workflow moving without manually handling primers at each cycle.

As a true single-stage press, the Sizemaster turns out roughly 4 to 6 boxes of shells per hour - a comfortable pace for trap shooters, upland hunters, and casual clay-target enthusiasts who reload modest quantities and want full control over each round. Three powder bushings (#20, #22, and #24) are included so common 20 gauge charge weights are dialed in right out of the box.

At approximately 19.5 lbs, the Sizemaster anchors firmly to the bench and resists walking under the reloading stroke. This is a complete, ready-to-use shotshell reloading press - a proven platform for keeping 20 gauge ammunition costs down for years of shooting.
