MEC has redesigned the 600 Jr., our most popular model and the world's top selling shotshell reloader, to include popular features found on our more expensive models. Novice and seasoned gunners will appreciate these new features along with the time-tested excellence this single-stage reloader has provided over the years with quick, simple operation and a minimum of effort. The MEC 600 Jr. Mark 5 can load eight to ten boxes per hour, and can be upgraded at a later date with the optional primer feed, which eliminates the need to handle each primer individually. The press is adjustable for 3" shells. Include die set, charge bar and 3 bushings.
