The shotguns that I prefer to use when shooting 50 yard ducks at 90 degree deflection would make hamburger out of the duck if the duck took the whole pattern. I will be very happy with the amount of shot that will intersect with the duck. My little 3 1/4 inch chamber 30" Sterlingworth shoots a pattern that seems absolutely destructive until about 60 yards. At that point the pattern is just kind of "pretty".
