MEC 600 Jr. Mark 5 Reloader 16 ga

The MEC 600 Jr. Mark 5 Reloader 16 ga is a single-stage reloading press designed for shooters who need efficient, reliable ammunition production. Manufactured by Mayville Engineering Company, this 16-gauge reloader combines straightforward mechanical operation with proven durability, making it an accessible entry point for dedicated reloaders who want to reduce ammunition costs without sacrificing quality control or consistency.

The MEC 600 Jr. Mark 5 delivers production rates of 4 to 6 boxes per hour, allowing serious shotgun enthusiasts to reload substantial quantities in a single session. The single-stage design—where each operation (resizing, priming, powder charging, and shot/wad loading) is performed sequentially—provides complete visibility into every round and enables precise adjustments between shots. The press can handle shells up to 3 inches and accepts upgrade kits that automate primer handling, eliminating the manual feeding that would otherwise slow workflow.

This reloader targets shotgun hunters and sport shooters who fire significant volumes of 16-gauge ammunition. Trap, skeet, and hunting applications all benefit from the ability to reload fired hulls and reuse them multiple times, creating substantial savings over factory ammunition.
