MEC’s Sizemaster is a single-stage shotshell reloading press built for .410 Bore shooters loading up to 3-inch shells, machined with compound leverage (brand part no. 81204103) to make resizing steel-head hulls manageable at the handle. This no-primer-feed configuration is set up for reloaders who prefer to hand-prime rather than run an automated primer feed on the press. It does not use standard shell holders, running instead on MEC’s proprietary charging system built around the .410 Bore. For shotshell reloaders standardized on Mec Reloading presses, this reloading press is a dedicated single-stage setup for .410 shells.
