I live only 30 mins from Blue Mountain, and although yes, it's a place to shoot, it's not that great of a place, IMHO.
Only open on Fridays, Saturdays and Sundays.
They don't allow offhand shooting of rifles, and enforce slow fire by making you only load one round at a time.
They take your driver's license number if you're shooting anything larger than a .22 rifle, and your pistol permit number if you're shooting handguns.
Unlike most ranges I've been to, the police you may find yourself shooting next to take an active interest in what you're shooting, but in a bad way - guys have been busted (arrested, not just told to go home for the day) for breaking AWB and mag capacity laws (State Laws).
There's a small private range on Ardsley Road in Scarsdale, of all places, but if you want to shoot there more than once you need to join ($125 annual fee), and you can't shoot muzzeloaders or rifles stronger than pistol caliber.
