The MEC 600 Jr. Mark 5 is a single-stage shotshell press built for reloaders who want straightforward, reliable performance on a benchtop. If you're loading 28-gauge 2-3/4" shells, this press handles the job with the kind of simplicity and durability that's made MEC a name trusted by shotgun reloaders for decades. It's engineered to keep setup minimal and operation intuitive—no unnecessary complications, just solid mechanics that cycle smoothly and consistently.

Speed matters when you're stocking ammunition, and the 600 Jr. Mark 5 delivers a realistic throughput of four to six completed boxes per hour, depending on your familiarity with the process and your setup.
