Peggy's been bugging me to buy her a reloader for a long time! I'd like to load center fires but the 410's would be great too (that's what my daughter uses when we shoot sporting clays). The 410's aint cheap for sure and 16 ga is almost impossible to find around here.
If you can get some 45 long colt, 45/70, 45/90, or 45/100 brass, they can be loaded as 410 slug and shot shells. As for the 16 gauge, it is hard to come by. I have 2 16's and finding shells is difficult, usually when I can find some there's only a box or two.
