MEC Super Sizer Die Set Converter To 28 Gauge

The MEC Super Sizer Die Set Converter To 28 Gauge is a precision ammunition reloading component manufactured by Mayville Engineering Co. that enables shooters to adapt their existing Super Sizer reloading press to 28 gauge shotshell specifications. This converter die set transforms a single-gauge press into a multi-gauge platform, eliminating the need to purchase an entirely new reloading system when switching gauges.

The die set contains the specialized tooling necessary to properly resize, prime, and seat components specific to 28 gauge shotshells. Reloaders working with 28 gauge—a lighter gauge used in upland bird hunting and competitive clay shooting—require precise dimensional specifications to ensure consistent performance and reliable chamber fit. The converter maintains MEC's engineering tolerances across gauge conversions, allowing shooters to maintain uniform reloading quality without recalibrating their existing press setup.

Shotgun reloaders who work multiple gauges benefit significantly from converter systems. Rather than operating separate presses for each gauge—a costly and space-intensive approach—the Super Sizer converter die set provides a cost-effective solution for shooters who load both 28 gauge and other available gauges (10, 12, 16, 20 gauge, and .410 bore). This flexibility is particularly valuable for hunters and clay sport competitors who rotate between different shotgun platforms throughout the season.

MEC reloading equipment is widely recognized in the shotshell reloading community for straightforward mechanical design and reliable component standardization. The Super Sizer platform's modular die system approach allows serious reloaders to build a versatile operation without premium capital investment, making it an established choice for both high-volume and occasional shotshell loaders.
