You can shoot at the Kenmore range to 100 yards. Every day from 12 - Dusk. About $12. Only single shot though. Only one round at a time allowed to be loaded.
For rapid fire and "ripping off a whole mag" you may have to resort to finding an open space on public land. Not a good time right now with all the snow.
BTW, Kenmore is closed Thanksgiving, even to members.
