The MEC Sizemaster Single Stage 20 Gauge Shotshell Reloading Press delivers straightforward operation without compromising on convenience or efficiency. The Power Ring collet resizer restores cases to factory specification, handling brass or steel heads and both high and low base shells. This single stage press combines a power ring collet resizer, cam-action crimp die, and Spindex crimp starter that swivels to align with original shell creases.
Set at the factory for 2-3/4″ shells and adjustable for 3″ shells, this press is engineered specifically for 20 gauge reloading. The included E-Z Prime primer feeder automatically dispenses primers, streamlining your workflow. The press produces 4 to 6 boxes of shells per hour and comes with #20, 22, & 24 bushings and a 7/8 oz. charge bar.
MEC has built its reputation on quality shotshell presses that serve reloaders at every experience level, from those new to the craft to veterans with decades of reloading behind them. Additional die sets are available separately, allowing you to change gauges as your reloading needs evolve.
