Well, I finally patterned my Nova and Briley x-full choke combo. I tried about 10 different shells and all were turkey killers at 30 yards. The Remington Hevi Shot in the 3 1/2" with # 6 was good, but only matched the Federal 3" Flight Control # 6's. Winchester Supremes in the 3 1/2 # 5's came in 3rd best. The Federals are half the price of the Remington Hevi shot, so they win. 20 hits average on the brain and spine with both (4 shots).
