I don't see it as a safety issue, but rather a noise issue. There were a number of houses nearby. I'll shoot on my 10 acres in MS, but I want to open up dialogue with my neighbors so that if they are working shift work or are home under the weather that I am not disturbing them. Mississippi has a law that would allow local governments to restrict centerfire rifle discharge on on parcels of less than 40 acres. Very few have.
