I voted 20ga, and I also know the 12 is more logical, I am a wingshooter with the shotgun and we no longer have enough ducks arround here to get my attention. I like the way the 20 (and really the 28ga) handle for me. I will never part with my 12 ga target and utility guns but give me a 20 to hunt with. For those shooting slugs and buck, the 12 is more logical as well as for turkey and ducks. My favorite shotguns are under 7 1/2 lbs, trim and lively. I bought a 20ga 425 as my "big" gun in 95 and still feel that way. I really like 410s and a 28ga is not far behind the 20 in performance in the uplands.If you dont reload for them, the 28 and 410 are off the menu due to shell cost. If you want to have a ball and save some money get a 410 870 and a MEC! For wingshooting the smaller bores with their smaller frames are outstanding, for using a shotgun like a short range rifle, go 12ga. Ducks and geese almost require a 12 with our current nontoxic laws, but we killed LOTS of ducks in the 70s with 20 ga shotguns and lead shot.
