Convert your MEC 600 Jr. Mark V to 20 gauge with this dedicated die set from MEC Outdoors. The set includes all necessary components: K.O. Bushing, Resize Ring, Deprime Punch, Reprime Punch, Wad Guide, Rammer Tube, Star Crimp Head, Cam Crimp Assembly, Shell Holder, and Drop Tube. Switching between gauges takes approximately 15 minutes, making it practical for reloaders who work with multiple shotguns.
The MEC 600 Jr. Mark V is adjustable for 3″ shells and available in 10, 12, 16, 20 and 28 gauge and .410 bore. Using simple single-stage operation, the press handles each reloading step with a single handle pull: depriming, priming, resizing the metal base, measuring powder charge, seating the wad column, measuring shot charge, and forming the crimp. This cost-effective conversion die set expands your existing 600 Jr. Mark V’s capabilities without requiring a second press, making it ideal for reloaders with limited bench space who want to load for different gauges economically.
