No question ORSA Oak Ridge Sportsmans Association. My first experience there was around 1953 shooting with my dad so it has a special place for me.
ORSA has nearly 1000 acres and about anything you'd want including a first class action setup, clays, trap and skeet. For rifles the have up to 1000yd and archery, benchrest, indoor pistol (no magnums), competition range, steel plate range and plinking range. There's a beautiful clubhouse as well. ORSA sponsors many matches and has all types of programs for 22rf up to service rifles.
