Film, if you're within city limits, it most likely won't happen. If you are in the county outside of city limits, check with your Sheriff Dept. Ask nicely and they may even send a deputy out to look over where you want to shoot. If you get a stamp of approval, keep your shooting time between 10am and 4pm. Stop by the neighbors that are close enough to be bothered by gunshots, and let them know you have a range on your property, what days you shoot, and the hours. You might end up with some new friends that want to shoot with you though.
