I have 17 acres in Caldwell Co. and spoke with the Sheriffs Office and the game warden to confirm everything was good and they said 10 acres or more and you are good to go. My neighbor kept saying that shooting at night was a federal offense which the Sheriffs Office and game warded stated is not true.
The Sergeant I spoke with also stated that even though it is legal to shoot, sometimes neighbors will call them to complain. He stated they usually send a Deputy out to make contact and make sure everyone is being safe.
Your neighbor sounds like he gets his information from TV shows and movies, or just pulls it out of his arse
