Not that we are the best shots in the world but after being pretty disappointed with our hit and miss ratio my duck hunting group and I did some patterning with our factory choke tubes. The group guns are (2) Benelli SBE 2's a Beretta semi auto and a Remington 870. The results were about the same with each gun tested with multiple different ammo manufacturers. The BB count at forty yards was terrible and not significantly better till tested at 25 yards. The question is... You that are avid waterfowl hunters, Do you hunt with after market specialty choke tubes?? If so what do you recommend?
