Oops, I did the same thing as MSP when I originally read your first post. I too missed the words "small game". If you take deer, geese, piggies, and the like out of the scenario I would opt for a 20ga. with screw in chokes. If 16ga ammo were as easy to find and the selection was as broad as it is for 20ga. ammo, that would be an option as well but until that happens I will stick to the 20ga.
