No one should fire a gun from their property, unless --
1.. they have a 240 degree backstop of earth,at least 6 ft highand graded to a decline to the front of 30 degrees
2.. The persons should have proper instruction in firearms safety
3.. You need to know where your bullet impact zone will be if you have a deflected bullet
The 22 caliber long rifle can carry for over 1 mile at elevated arc.
therefore 500 ft would not make a diference.
A 308 caliber rifle can kill at 1000yards, I know I was in the Army,and made 1000 yard shots on a calm day. Therefore again 500 feet means nothing.
Build a 200yard well banked target range ,make it a membership only
club, and have a safety range master moniter members.
Thats my input
