I use nothing but Federal blue box, 3", #2's at 1550 fps.
Up to 54 ducks and 2 geese so far, and no lost birds.
A great dog helps.
I also don't sky bust. 30-35 yards is my furthest decoy. Anything past that, I wait til they come around again.

Later, I do switch to bb's when going after well feathered geese.
Factory Remington extended modified choke always.
