Mec Super Sizer .410 Bore -$225.70
Availability: In Stock
The Mec Super Sizer 12Ga is a dedicated shotshell case prep tool built to restore fired hulls to factory specifications. Whether you're a new reloader just setting up your bench or a seasoned hand looking to upgrade, this sizer handles the critical first step of shotshell reloading—bringing the base of your 12-gauge empties back to their original dimensions so they'll chamber and perform reliably in your shotgun.
The core innovation here is MEC's Power-Ring collet resizing device, which does the heavy lifting for you. Eight sturdy steel fingers encircle the shell base and apply even, consistent pressure as you work the ram. This multi-point contact ensures the base gets resized uniformly—no pinching, no high spots—which matters when you're counting on consistent chamber fit and reliable function downrange. The process requires minimal effort thanks to the intelligent lever geometry, so you won't fatigue your hand or wrist during long reloading sessions.
Built from durable steel throughout, the Mec Super Sizer is designed to accept shotshells of any length, making it versatile across different load types and your hunting or sport-shooting needs. All mounting hardware comes included, and the unit integrates seamlessly as an upgrade to conventional MEC reloading equipment or as a standalone station in your setup. This is the kind of tool that pays for itself in consistency and saved labor over the course of a few hundred shells.
