I shoot a Beretta 391 20 gauge. My girlfriend shoots a 390 20gauge. We have shot both ducks and geese with them. We keep our shots inside 40 yards.... no issues.

I like Hevi-shot #4s for geese. Even for decoying geese with the 20 like an Improved Modified choke tube.

For ducks, Kent Fast Steel 3" 7/8oz of #2 or #3 at 1550fps. I like the Light mod choke in my gun, Rebecca shoots an IC.
