MEC 600 Jr. Mark 5 Reloader 410 ga 2.5"

The MEC 600 Jr. Mark 5 Reloader for .410 gauge 2.5" shells is a single-stage reloading press engineered for shooters who demand precision and efficiency without complexity. Manufactured by Mayville Engineering Company, this compact benchtop reloader combines straightforward operation with the speed necessary for consistent, high-volume ammunition production—capable of processing four to six boxes per hour depending on the operator's pace and familiarity with the press.

The Mark 5 design prioritizes accessibility for reloaders working with smaller gauge shotgun ammunition. The single-stage platform means each round progresses through one die station per stroke, allowing the user to inspect cases and handle primers individually—a critical control point for quality assurance in shotshell reloading. The press accepts standard .410 gauge components and dies, making it compatible with the existing reloading infrastructure most shotgun enthusiasts already maintain. Optional upgrades are available for operators who prefer automated primer seating, reducing the manual handling that characterizes traditional single-stage operation.

This reloader is built for handloaders who shoot .410 bore ammunition regularly—upland bird hunters, clay shooters, and sport shooters who value cost control and component consistency. The 2.5" shell specification matches the standard chamber length of most .410 shotguns in circulation. At 13.72 pounds with a footprint of 17 × 9.2 × 22.6 inches, the MEC 600 Jr. fits easily on a standard reloading bench alongside other equipment without consuming excessive workspace. Serious reloaders appreciate MEC's reputation for durable, user-serviceable equipment that performs reliably across thousands of cycles.
