The MEC 600 Jr. Mark 5 Single-Stage Reloader (MEC part no. 8447410) is a dedicated .410 gauge shotshell press built for the home reloader who wants consistent, factory-quality hulls without a progressive-press learning curve. MEC Outdoors has built shotshell presses for generations of clay and upland shooters, and the 600 Jr. Mark 5 carries that reputation into the smallest, most demanding gauge on the bench. Every station works off a single steel frame, so cases move through resizing, priming, charging, and crimping in a controlled, repeatable sequence. It is a strong choice for shooters loading their own .410 target and field loads in bulk.

Key Specifications

• Chambered for .410 bore shells, giving small-gauge shooters a press sized specifically for their cartridge.
• Built as a single-stage shotshell reloading press, so each operation is performed deliberately for consistent results.
• Uses a multi-size thread pattern, keeping the press compatible with MEC’s standard bushing and charge bar accessories.
• Adjustable to load up to 3-inch shells, covering standard and magnum .410 hull lengths.
• Features a cam-action crimp die that returns every finished shell to its original factory crimp shape.
• The wad-guide station is designed for quick, easy wad positioning, keeping the loading cycle moving smoothly.
• Rated to load 4 to 6 boxes per hour, a realistic pace for a single-stage press run by one operator.
