The Mec Super Sizer Die Set Converter to 10 Gauge lets you expand your existing Super Sizer press into a multi-gauge shotshell reloading workstation without buying a whole new machine. If you already own a Super Sizer press and want to load 10 gauge shells alongside your current gauge, this die set converter is the efficient path forward. Swapping die sets is faster and cheaper than investing in additional presses, making it a smart move for serious shotshell handloaders who run multiple gauges.
MEC (Mayville Engineering Co.) has been the go-to name in shotshell reloading equipment for decades, and their Super Sizer line is built around durability and consistency. The die set converter maintains that reputation—it's engineered to work seamlessly with your existing Super Sizer platform, so you can trust the quality and fit. Whether you're a turkey hunter who prefers 10 gauge or a waterfowler looking to diversify your ammunition options, adding 10 gauge capability to your reloading bench is straightforward with this converter.
Before ordering, confirm that your current press is indeed a Super Sizer model and that you have the press on hand to ensure compatibility. Die set converters are gauge-specific, so this one is designed exclusively for 10 gauge reloading. If you're new to shotshell handloading or have questions about the changeover process, our team at the counter is happy to walk you through it.
