I have recently started to hunt geese and ducks and I am in the market for a new shotgun. The question I have is this: is it worth getting a 3 1/2" gun or should I stick with a 3". Is the 3 1/2" much more effective for longer shots, or should I stick with a 3" gun and invest in a good choke tube? Any help would be appreciated. Thanks and Happy Holidays!!
