Wouldn't those rules apply to a public range? If it is private, not sure the same rules would apply. That is about like saying you have to have 100 acres to shoot a deer.
No. The Peoples Republic of Clarke County has similar rules. They don't have an acreage limitation per se, but the setbacks for discharging a firearm effectively create them. Lots of bow hunting in Clarke County. The one gun club and firing range are grandfathered in.
