Shotgunjones, my friend Joe Taylor mentioned "lively stock design", not actually addressing gun or barrel weight. I think he may be describing the type of stock that I mentioned previously, a little shorter and a little more drop than the typical ATA trap gun. Joe's bird and pigeon guns are not trap style guns on the back end, nor are mine. In my opinion, for anything other than ATA trap shooting, the shortest stock that can be comfortably used without nose to thumb contact is the "liveliest" style. Murphy
