The MEC 600 Jr. Mark V Die Set, 20 Gauge (brand part no. 845220) converts an existing MEC 600 Jr. Mark V shotshell reloading press to 20 Gauge, letting shooters who load more than one gauge add a second chambering without buying an entirely new press. MEC built the 600 Jr. Mark V around exactly this kind of gauge-conversion flexibility, so the die set drops into your current press body and handles the resizing and crimping steps specific to 20 Gauge hulls.
