I want to start reloading my own shot shells. Both 12 and 20 gauge. I like the MEC 9000 but I can't tell if the 9000 will do both gauges. I can't afford to buy two presses. Any advise on which progressive presses (brands) will do both gauges for the best price. I would assume (but don't know) that some parts would be switched to go back and forth between gauges. Thanks for the help for a new member and sorry if this subject has been posted already.
