I have been using a 20 gauge over and under for many years for pheasants. I use three inch shells. I also have a 12 gauge Beretta 686 that I use occasionally, but I prefer the 20 Orion because of weight. My question for all the other over and under crowd is, what are your choke tubes that you use? I have had fairly good success with skeet over improved but I am curious to the opinions of others. Thanks, John
