MEC Super Sizer 410 Bore Shotshell Resizer

The MEC Super Sizer is a dedicated 410 Bore shotshell resizing tool that brings fired hulls back to factory specifications so they drop cleanly into chambers and feed smoothly through magazines. Built around MEC's exclusive Power-Ring collet sizing device, the unit uses eight steel fingers that encircle the base of the hull and apply even pressure to resize both low and high brass shells to original factory dimensions in one easy pull.

The Super Sizer accepts all shotshell lengths and works as a standalone reloading accessory or as an upgrade to a conventional shotshell reloader. Its steel finger and collet construction delivers consistent, even resizing on every cycle, making it a practical addition to any 410 Bore shotgun reloading setup.
