most clubs won't let shoot a shotgun, machinegun or highpower rifle on the indoor range. you can on the loeb range. love those fudd rules!
Shotgun: slugs only. If you shoot buck or bird shot, someone will have a stern talk with you.
But yea, Loeb is a pretty good range. My only complaint is that there should be sound absorbing material on the ceiling and walls for at least the first 20 feet, it can get wicked loud in there.
