If you don't mind driving about 50 minutes to an hour go to the Manatee Gun Range.
There are Range Nazis (I am one) but we mostly just make sure things are safe. Stuff like making sure you keep the weapon pointed down range and not touching your weapon when the range is cold. We like for you to pick up your brass before you leave. As long as you don't do something really stupid you can shoot and have a good time. Nobody is going to harass you. We are black rifle friendly.
We go cold about once every half hour so people can check their targets. We don't like people shooting cross range or up in the air but other than that and not shooting at somebody else’s target nobody will bother you. We have a regular range, full auto range, bench rest range and 1000 yd range. We also have a shotgun range and a couple of cowboy shooting ranges. If you are not a member it will cost you $18 for the day which includes a target.
If it bothers someone to adhere to basic shooting safety precautions then they need to stay off the public ranges and buy themselves some property some place to shoot. I am sure that doesn't apply to you.
