Mec Super Sizer Die Set Converter To 16 Gauge
The Mec Super Sizer Die Set Converter To 16 Gauge is your ticket to reloading shotshell ammunition in a different gauge without buying a whole new press. If you already own a Mec Super Sizer and want to expand into 16-gauge handloads, this die set converter lets you swap gauges and keep your existing press platform. Whether you're loading for a vintage 16-gauge you picked up, looking to reload for a friend's gun, or rounding out your ammo options, this converter keeps your investment focused where it matters — on quality reloads, not duplicate equipment.
Shotshell reloading demands precision, and a dedicated die set for your chosen gauge ensures proper sizing, seating, and crimping. The 16-gauge converter is designed to work with your Super Sizer platform, making the transition straightforward for reloaders already familiar with Mec equipment. This approach also gives you flexibility: keep your main press set up for your primary gauge and convert when the 16-gauge job comes up, or maintain a semi-permanent setup if 16-gauge is your main load.
Mec has been in the shotshell reloading game for decades, and their Super Sizer line is built on proven mechanics. A dedicated die set for 16-gauge is the responsible way to ensure your reloads meet chamber specs and perform safely in the field or on the range.

Frequently Asked Questions
Will this die set work with my existing Mec Super Sizer press?
Yes — this converter is designed to work with your current Super Sizer platform. You swap out the die set to change gauges.
What gauges are available in the Mec Super Sizer converter line?
Mec offers Super Sizer die set converters in 10, 12, 16, 20, 28 gauge and .410 bore, allowing you to expand your reloading capabilities across multiple gauges.
Do I need a separate press to reload 16-gauge, or just this die set?
You'll need an existing Mec Super Sizer press. This converter die set changes the gauge capability of that press — it is not a standalone reloading system.
