MEC 600 Jr. Mark 5 Single Stage Shotshell Press - 12 Gauge, 2-3/4" & 3"

The MEC 600 Jr. Mark 5 single stage shotshell press is a straightforward, no-frills reloader built for shooters who load 12 gauge ammunition in both 2-3/4" and 3" lengths. If you're serious about keeping your shotgun fed without the markup of factory shells, this press delivers solid, repeatable results at a pace that won't leave you chained to the bench. It's the kind of workhorse tool that's been trusted by reloaders for decades—simple enough that you'll spend your time actually loading, not fighting complicated machinery.

Single-stage presses like the MEC 600 Jr. do one operation per pull of the handle, which means you're fully in control of every round. That deliberate pace also means you catch mistakes before they become problems. If you're new to shotshell reloading or you reload in modest quantities—say, enough to keep your shells in stock between seasons—this press won't overwhelm you with complexity or cost you extra for features you don't need. The MEC 600 Jr. Mark 5 handles both standard 2-3/4" and magnum 3" shells, so you're not locked into one hull length.

The press is engineered to cycle at a practical pace of four to six boxes per hour, depending on your familiarity and setup. If your workflow evolves and you want to reduce primer handling, upgrade kits are available to speed that part of the process. It's the kind of flexibility that keeps the tool useful as your reloading habits change.
