Mec 812028 Sizemaster Shotshell Reloading Press Cast Iron

The MEC Sizemaster is a cast-iron single-stage shotshell reloading press built for shooters who process volume. If you're running clay targets, hunting upland or waterfowl, or stocking your own field loads, this press handles both 2¾-inch and 3-inch shells with the same straightforward, no-nonsense approach MEC has refined over decades. The cast-iron frame delivers the rigidity serious reloaders need, and the long-stroke mechanism works equally well whether you're loading light target rounds or maximum-velocity hunting loads.

The Sizemaster's adjustable resizing chamber and cam-operated crimp system give you control over each stage of the reload without fussy adjustments between batches. The flip-top measure design speeds your workflow, and ambidextrous operation means lefties aren't fighting against the machine. The press ships ready to work—it comes with the crimp starters (Spindex2) you need to get started, so you're not hunting down additional parts before your first batch.

This is a press for people who understand that consistency and durability matter more than gadgetry. Whether you're a competitive shooter chasing repeatability or a hunter keeping your freezer full, the Sizemaster's straightforward design and proven track record make it a solid workhorse on any reloading bench.
