The "normal" angles described on the webpage linked by archer are the golden angles for high flying planes speficially for that AA gun. The golden angle is the angle where your shot remains at normal plane flying altitudes for the longest time. So there's some range differences for each gun type, as their golden angles' range differs. And the low golden angle shots on the website are for those low flying torpedo bombers.
The first decent AA gun are the rapid fire 2x3" at lvl 34. Then comes the plane sniping guns 2x4.7" and 2x5" at lvls 36 and 48. So you have some leveling to do. And make sure you're using manual aiming, and not auto. Since you can't control your gun angles with auto aim.
