A new gun or new to you, Wired? My guess is most gunners here are using older doubles, some twist and damascus, and low-pressure 2-2 3/4-inch loads for waterfowl; all they need for birds over decoys.

Hang in to the board and you'll get all the advice you need on choosing a gun, new or used. All of my guns are relatively old, the newest was made 40-odd years ago. I'm not handicapped by any of them, in any way.
