bf 109 sighting in distance

[black out]

Ive been searching the net for some time now, but cant find the distances at which the bf 109 was sighted in. I know they shot fighters at close range and bombers from further cuz they are bigger have gunners. Were the cannons sighted in diffrently from mg's cuz of different velocity? Any input is apreciated.

Thanks, so according to the chart Mk 108 and mg 131 were sighted in @ 400 meters and the 20mm @ 500 meters because it had better velocity?

Nope. Because of the different ballistic trajectory.
