Mec 600 Jr. Mark V: This single-stage shotshell reloading press is designed to make reloading easy and affordable. The Mark V performs all of the basic reloading steps with a simple pull of the handle, including depriming, priming, resizing the metal base, measuring the correct amount of powder, firmly seating the wad column, measuring the precise amount of shot, and forming a tightly sealed crimp. The Mark V is also highly versatile, capable of loading both lead and steel shot shells.
