MEC's
I own reloading setups in all 4 guages - I have all MEC 9000 machines except for the 12 Guage which is Hydraulic. I would recommend the MEC 9000 for the 28 and 410. With the price of new shells in those guages, you will recoup your initial investment quickly. After you get the press setup, you should be able to reload 400-500 rounds per hour at a relaxed pace - including adding powder, shot, and primers every hundred rounds. As with all MECS regardless of model, the hard part is setting the maching up properly. On MECs the primer drop seems to give the most trouble, but once adjusted, should not be a problem. Used machines are available, but check the price of new- if not a substantial discount, may as well buy new. The machines will last a long time with minimal repairs. (an occasional spring, or plastic wad guide may break)
