MEC 600 Jr. Mark 5 Reloader 28 ga

The MEC 600 Jr. Mark 5 Reloader for 28 gauge is a single-stage shotshell reloading press engineered for consistent, efficient ammunition assembly. Manufactured by Mayville Engineering Company, this reloader delivers a straightforward operational design that prioritizes repeatability and speed—loading between four and six boxes per hour depending on shooter familiarity and setup. For handloaders working with 3-inch 28 gauge shells, this press combines proven mechanical reliability with the simplified workflow that single-stage systems are known for.

The Mark 5 platform accommodates the precision requirements of shotshell reloading, where consistent primer seating, powder charge, and wad compression directly affect pattern density and shot placement. At 13.63 pounds with a footprint of 17.2 x 9.3 x 22.4 inches, the press sits compactly on a standard reloading bench without demanding significant workspace. Users can optionally upgrade the primer system to eliminate manual primer handling—a practical advancement for those processing higher volumes. The press's mechanical advantage and simple lever operation make it accessible to both newcomers and experienced loaders seeking to reload specialty 28 gauge loads that may be difficult to source commercially.

This reloader is purpose-built for 28 gauge handloaders who need to customize loads for upland hunting, clay target shooting, or sport loads tailored to specific shot patterns and ballistic preferences. Single-stage presses like the MEC 600 Jr. Mark 5 appeal to precision-focused loaders who prioritize quality control over maximum production speed. Whether developing match loads for competitive shotgun sports or assembling hunting ammunition optimized for your particular shotgun's characteristics, this press provides the mechanical platform and operational simplicity to achieve repeatable results batch after batch.
