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. This press is ideal for handloaders looking to customize loads for upland hunting, clay target shooting, or sport loads tailored to specific shot patterns and ballistic preferences.

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 various shooting applications. Its design emphasizes reliability and ease of use, making it a valuable tool for anyone looking to enhance their reloading experience.
