Advice needed on getting 4H shooting education BB guns (Daisy 499) shooting tens. Guns are weighted to the full 6 pounds. Ammo is sorted by size and weight. Test shooting is done from rock solid sandbags/rest. I have 10 different shot tubes to tinker with. Triggers have been worked to one pound. Still shooting 8-9s. Ball bearings, HBN coating, honing the barrel are all being considered. I can shoot better groups at 100 yards than I can at 5 meters. Help!
