BB for geese and 3 or 4 for ducks ( be careful not to mix a BB on with your duck loads cause they can realy tear up a teal

I use 2s and 4s. Mostly 4s. Sometimes we get a flock of geese comin in. 4s work if your close enough but 2s will take down a goose much easier. We see alot more ducks and 2s do alot of damage on ducks. I like heavi shot. Have used blask cloud too.

I like Kent #4 FastSteel for ducks and even kill quite a few geese with the load over decoys. For a stand alone goose load the #2 Federal Black Cloud is very effective.

Depends on how your hunting. Geese I like BB. For ducks I get a little more varied. Pass shooting or if you are going to have further shots I will go with 2s. Over decoys and nice close shots I go with 4s. If I am hunting a place where I may have a variety of shots I go with 3s.

I don't really have a preference on brands although I always check the shot speed. I like faster shots, like 1550 fps.
