I would recommend calling Kolar to get the best answer. With that said, Target Shotguns has this on their website regarding barrel hangers.I'm a new Kolar Max Lite Sporting owner. As I understand it, changing the front hanger primarily affects the lower barrel. Approximately how much does each hanger change move the POI of the lower barrel at 40 yards?
Target Shotguns said:Changes POI at 30 yds by 2 inches when down in number from the hanger currently on your barrels.
Example: if your gun currently has a #4 hanger, change to a #3 if you want your bottom barrel to shoot 2 inches higher at 30 yards. Change to a #5 if you want the bottom barrel to shoot 2" lower at 30 yards.
