Just an idea to throw out at the OP:
Contact the NRA about setting up some classes, work with the range to see if you could be an instructor. Gather what resources are available and use them to increase the awareness of people around you.
Obviously you have some gun sense, because you are concerned. I stopped shooting at public ranges (and hunting on public land) for the exact same reason you stated. Too many youngster's have learned to shoot watching videos on the internet, from movies ("I want you to try to curve that bullet."), and video games.
Legally they are able to own a firearm, but many of them are not mature enough to understand the responsibilities that go with firearm ownership.
You have identified a need, try to do something about it. (I leave hunter safety flyer's and training course info at the public ranges even though I do not shoot their any longer. It also gives me a chance to pick up extra brass.
