I have a friend of mine who has 10 acres in Gwinnett county. One day when he was out target practicing a Gwinnett county cop came by and told him he had to be 500ft from a public road to discharge a firearm. In the DNR regulations it says 50yards. Does anyone know if there is some county ordinance that supercedes the DNR regs.? Any Gwinnett county Police out there feel free to enlighten me. His address is Sugar Hill but he is not in city limits. He personally checked it out at Sugar Hill City Hall.
