I have went through a full box of 3" #6 shot . The first bird I took with them , I misjudged the distance since the bird came in across an open field . I shot when I felt like he was in range and the bird dropped on the spot . After the shot I ranged him at 50 yds ! I would not have taken such a long shot normally , but the extended range ammo dropped him in his tracks. I shot 6 birds out of that box of shells and every one hit the ground hard . It will be in my vest again this spring !
