The MEC Sizemaster Single-Stage Reloader for .410 bore (MEC part no. 8120410) is the .410-specific configuration of MEC’s proven Sizemaster platform, built without an integrated primer feed, so priming is done manually rather than automatically as on MEC’s larger-gauge Sizemasters. The Power Ring collet resizer still returns every hull base to factory specification whether you’re running brass or steel heads, high base or low base, and the press is adjustable to load shells up to 3 inches. It ships with a 1/2-ounce charge bar suited to typical .410 loads, and a single operator can expect to load roughly 4 to 6 boxes per hour. For .410 shooters who don’t need automatic priming, it’s a straightforward, no-frills way to reload the smallest shotgun gauge.
