I can say with certainty that the right choke paired with the right shot size can give a clear advantage when hunting waterfowl. A tight choke paired with #2s can really bring them down. Killing them dead is a whole nother matter. Even a well hit duck within 30/40 yards can still be very much alive when they hit the water. Many that are taken down from high above require a follow up shot. If their head pops up after they hit the water, they get a follow up shot. When they are flying a bit high, I like a long range Patternmaster along with #2s. When they are within the decoy spread, I like #3s or 4s and a short range choke. My Patternmaster chokes don't list the chokes as full, mod, imp cyl etc. My guess is a Patternmaster long range is about the equivalent of a typical modified. Extra long range would be an improved modified. We love the days when we have the short range chokes in. It typically means they are decoyng in. All this opinion is relative to hunting flooded timber.
