LeFusil is right, as far as he goes. BUT.....the ballistic superiority is really an illusion. I can kill anything but pheasants and ducks just as dead with a 7/8 oz in a 20, and I don't want to shoot stiff loads in a light gun. The big factor for me is that light 20's are far more available in low priced guns. My light gun, an SKB 100, has been with me for almost 15 years (I'm 74 now.). It weighs 5 lb. 12 oz. It cost the princely sum of $925 used, and is probably still worth $750 with all the scratches I've put on it. And most importantly, I didn't have to worry about it when I carried it in the swamp, in the rain, or on rocky slopes. That wouldn't have been true for any 2 1/2 inch 12 that I am aware of. They tend to be pricey!
