Got a few newbie questions . Can a Mec 600 Jr. Load steel shotshells. I looked on the mec sight and it lists steel shot charge bars for single stage presses but doesn't specify wich ones. Also how do I know wich charge bar to get for steel. I plan on loading 3" steel using #2 and BB and 2 3/4" lead using #6 and 8 shot. How do I tell wich powder bushings to get also. What are some good books to get?
