I'm looking to buy a new gun I mostly pheasant hunt but have been getting into waterfowl the last few years mostly geese, but I also hunt deer. I own a nova and like shooting it but I am looking for a new autoloader and was wondering how the SBEII would work for an all around gun since I would be trading in the two shotguns that I currently hunt with to make this purchase a little easier on my wife. Can I also get a deer barrel seperate? My next question is have any of you shot a winchester superx3 and how do they compare to the SBEII? I really like my nova and wouldlike to stay with Benelli but I have heard some other people talk about the winchester and I was looking for some input from some Benelli shooters. Thanks for any help.
