Have used it on Pheasants out of a 28 Gauge with 9 shot. It was impressive....
All shot at 55 yards is dropping....
Smaller shot will no doubt drop more, but since the density of TTS make it carry like lead 5's the difference will not be that great...

(lead 7.5's drop 5 feet at 110 yards and lead 9's 5 feet at 104yards. When fired from the horizontal. At 50 the difference would be insignificant . TTS 9's being more dense would carry better than lead 9's)
It would take a fine and highly experienced eye to notice any difference on a move, mount, shoot presentation at varying distances.
