Hi everyone new to the site. Looking for some advice on choke tubes. Are their any after market choke tubes that I can shoot steel through that people recommend? I am looking for a duck hunting choke tube to use for my SBE II for extended range. I am somewhat reluctant to buy one with out a little advice. I am not getting the kills that I want with the factory tubes. I have not had my gun long. Last year was the first season that I hunted with it and was not pleased with the amount of birds I was able to get. I realize probably a lot of that is due to operator error and getting used to the new gun. I also found a bulge in my barrel last year and had to send away for a new one. I do not have a lot of confidence in my benelli right now but I am trying hard not to give up on it yet. Any help would be great.
