Yeah I really do not intend to use them but figured I would check ballistics, I have an old single 20ga that is not marked and I assume it is 2 3/4 only so since I had some 1 oz. 8s I use for dove I figured I would ask. Last two birds I killed with a gun were under 20 yards, heck one was 5 yards so why not hunt with something that limits you, I typically bow hunt anyway!
