I use to have a 3 1/2 inch gun . I used the heck out of it, in every shell size possible and what I found out was is that I could kill just as effectively with a 2 3/4 inch shell. What the heck was I doing carrying all this extra weight. Started shooting the 20 at the duck blind and had no problems. Actually shot a little better because I was quicker getting on the bird and my swing was smoother and faster. Then took it out goose hunting and was impressed. For upland now I have been using a 28 almost exclusively for 2 years now. I am not wasting all that lead or steel now with these smaller bores. I think I am a better shot then I used to be now. I still shoot my 12 on occasion because that is just what we all do, shoot all of our guns. It is just fun taking the littler ones out. If I was going to pass shoot, then I would for sure take the 12 . Glad season is upon us for sure!! Have a goon one!!
