The Mec Reloading Die Kit for Model 600 Jr. Mark 5 is a complete conversion kit that lets you reload multiple shotgun gauges on your existing MEC 600 Jr. Mark 5 press. If you're a shotshell reloader who wants to expand beyond your current gauge without buying a second press, this kit gives you the tooling to swap calibers quickly and reload 10, 12, 16, 20, and 28 gauge shells, plus .410 bore. It's a cost-effective way to keep your reloading bench flexible when you shoot different shotguns across seasons or disciplines.
MEC (Mayville Engineering Company) has been building reloading equipment for decades, and this die kit reflects that pedigree—it's manufactured to work reliably in a press that's already proven itself in thousands of reloading rooms. The kit includes everything you need to make the conversion: a KO bushing, deprime and reprime punch, resize ring, star crimp head, cam crimp assembly, wad guide, rammer tube, shell holder, and drop tube. Just swap in the appropriate components for your target gauge, and you're ready to load.
Whether you're loading for upland birds one month and clay sports the next, or you own multiple shotguns in different gauges, having one press that handles them all beats the space and cost of dedicated single-gauge machines. The kit comes with instructions to walk you through the conversion process, so setup is straightforward even if you're new to gauge changes.
