All good thoughts gained from many years making your own.

I have two MEC Sizemasters, a 12 gauge and a 20. I load 1/2 and 3/4 ounce lead loads in both 12 and 20 gauge and two hull lengths: 2 1/2 and 2 3/4 inch. Both MEC's are mounted on a 3/4" wood base and I do all my loading with the press sitting in a 18" by 18" by 2 inch high box. Limits how far spilled shot and the occasional loose one goes. But once in a while, one still gets away.
