I have been playing with this load again, in my Benelli M1. I tried various choke constrictions with chokes from Kick's Carlson's, etc., but was not really getting anywhere. I ordered up a Kick's Buck Kicker 0.680 choke (since that about perfectly matched the diameter of the payload, and although the wads look MUCH better than the other chokes, I still had one flier that never hit the target board. I decided to dig out all of my old factory chokes, and measured them up. The factory Full was 0.685, so I decided to test it. All 3 balls right near point of aim at 35 yards in a perfect 4" Triangle. It is amazing how much difference 0.005" makes! I'll be testing it more at 50 yards and beyond.
