MEC Super Sizer Die Set Converter To 410 Bore

The MEC Super Sizer Die Set Converter To 410 Bore is a specialized reloading component designed to expand the versatility of an existing MEC Super Sizer press. This die set allows shooters to convert their current reloading equipment to handle .410 bore shotgun ammunition, eliminating the need to purchase an entirely new press system. The 410 bore conversion represents one of several gauge options available in the MEC Super Sizer die set lineup, making it an economical choice for reloaders who want to expand into smaller gauge shotgun production.

Mayville Engineering Company has established a solid reputation in the shotshell reloading market for producing straightforward, reliable progressive and single-stage presses. The Super Sizer die set converter maintains that same engineering approach—a purpose-built tool that integrates seamlessly with existing equipment. The .410 bore specification is particularly valuable for reloaders working with smaller gauge ammunition, where ammunition availability can be limited and reloading becomes a practical necessity. Compatible with MEC Super Sizer platforms, this converter kit enables users to maintain consistent shot sizes, powder charges, and velocities specific to .410 bore specifications.

This die set is engineered for reloaders who work with .410 bore shotguns used in small-game hunting, pest control, or specialized sport shooting applications. Rather than investing in duplicate equipment, users can swap die sets to maintain a single press station capable of producing multiple gauges. The product weighs 0.53 lbs, making it portable and suitable for workshop or mobile reloading setups. MEC Super Sizer die set converters are available in 10, 12, 16, 20, and 28 gauge options as well, providing complete gauge flexibility within the Super Sizer system architecture.
