With all due respect to the naysayers a 20 or even a 28 for waterfowl is not for everyone. But then again I'm not breaking wings or body shooting them. I take pains to have the best decoys spread possible and I consider myself an above average caller. If I can't get them to commit to within 40yds. I won't shoot. But when I do I take head shots. I shoot loads of clay targets to practice for hunting season and with a little bit of practice anyone can learn to focus on the leading edge be it a clay bird or a game bird.
When lead was legal, a 20 was all I shot. Now with the advent of the improved Bismuth and Tungsten Matrix the smallbores are back in business.
Scott, Mark and the rest of you smallbore waterfowlers enjoy your season.
