you CAN do it. my dad grew up in southern ID and he killed many many pheasants and huns with his 410, HOWEVER you are gonna need a goo dog as your number of cripples is sureto go up.
shoot you pattern board at the distance you plan to shoot. typically SxS guns are regulated to a given distance ie, they might hit left of sight to 20 yds, right on from 20-30 and start going right of sight beyond that.
