I'm not a bad shot in 5" guns.. most of the time i can hit bombers and jabo from 3.0, sometimes 4.0 if i can track it long enough.. If it's flying straight away i can hit from 5.0 and farther pretty consistantly.. heck, i can fire blindly into a swarm of black dots and get kills.. Fairly easy to down planes, but you can see the big 5 inch tracer (the gunner can't, you can) tracking ya if you're lookin for it
