The MEC 600 Jr Mark 5 single-stage shotshell reloading press (MEC part no. 844710) is configured for 10 gauge shells with a 2 ounce charge bar, giving big-bore shotgunners a straightforward way to load their own ammunition on the bench. Like the rest of the 600 Jr line, it uses MEC’s compound-leverage frame for quick, simple operation that turns out 4 to 6 boxes of shells per hour. The press is adjustable for 3-inch shells and can be upgraded later with MEC’s 285 CA primer feed, which removes the need to load primers by hand one at a time.
