Rocketman: No offense taken. My 5 1/2 lb 20 b balances on a string, or teeter totter about one inch ahead of hinge pin and feels good between the hands. It is not butt heavy nor barrel heavy. By teeter totter method, my close to 9 lb K-80 balances in a similar location. It also feels good between the hands. While it is not terribly difficult for me to shoot 100 straight skeet targets with the Krieghoff, it is very challenging for me to shoot 25 straight with the light little Holland, although I have on occasion....usually I average 22/25 or thereabouts with the lighter gun. When I miss the sight picture looks good, therefore I am assuming I am stopping the gun. In general, a light game gun is much more difficult to maintain consistency with and I would suspect Joe with his 4 lb shotgun would even have more trouble maintaining consistency than I do with my 5 1/2 lb 20 bore, certainly much more than I have with the 9 lb Krieghoff. I am very interested in your data base and would be thrilled to have you measure a couple of my guns and explain your system in greater detail. Thank you. Buzz
