I'm a 2's or 3's guy - 3's early and when there are lots of smaller ducks. When the teal and woodies are gone, and the flight mallards and divers predominate, I go to 2's. Early season geese fall to either with head shots. To quote my grandfather, "You have to shoot them in the face!" Later, I go to BBBs for the northern Canadian geese with bullet proof vests ;-)
