The public range that my brother and I go to is owned by the county and ran by the Missouri Conservation Dept or Game Wardens. They ask if you have used the range before, including kids. If NO is the response they go through the rules and that is it. As long as your a responsible person, and keep the muzzle down range or in the rack and pick up your spent brass it's fine. Shoot they even come over and talk or give some pointers if needed.
