Caleb,
While a press can be set up for various loads, it can be a pia going from one to another of varying column height. It's not economical to reload 12 or 20 ga. field loads as the cost of commercial is hard to beat reloading. Pick out a load you think you'll use more than others, one that would be expensive to buy off the shelf and set it up for it. It is not worth the expensive of buying and swapping out gauges as you can typically find a press in the gauge for less than the dies would cost. Gil
