Great info, the place I would be hunthing them would be small river no decoys so I'm not sure what kind of shot recommended I should use. I do have 870 in 3.5 magnum if that helps your recommendations. I would prefer to use lead as it is better on the teeth if I happend down upon some shot.
jmiller- did you take the picture in your avatar?? That is a great one!
No, I wish. I prefer to shoot them with other things though.
