I'm new to waterfowl hunting and have gone goose hunting in farm fields a few times, and will be doing some more here this fall. The other guys I hunt with all have Benelli Super Black Eagles and use 12 ga. 3 1/2" shells. I have a Benelli M2 that shoots 12 ga. 3". Am I under gunned or am I ok? I shot one duck so far but have not had a chance to shoot at any geese yet. I have been carrying 3" Black Cloud BB.
