I have not tested this, but you got to think that the Fed HW with the flight control wad would give you a better number. The question is...how far. I patterned the Fed HW #7 in 2 3/4 with a .570 choke and based on the numbers, I would not shoot that pattern beyond 30 yards. The Imp cyl may make it more of a 20 to 25 yard. It would be a great gun if you were using decoys and could pretty much guarantee the birds would get to the distance you want.
