Ive learned not to be cheap when it comes to goose loads, spend the money and buy hevi-shot or tungsten. They are worth it, Ive had WAY to many geese fly away laughing after I shot their armor plated bodies with lame steel only to have it bounce off them. Tungsten however takes them right out of the air. As far as ducks go I like to shoot a modified choke and 3in steel 2s work magically. If I am shooting through brush I will throw in some 3 inchBBs to help knock them down.
