I'm talking about dogfights against fighters, Anarchy.
After 300m, landing a 30 mm shell is far more difficult with such Balistic.
"The resulting low muzzle velocity was the MK 108's main shortcoming, with the result that its projectile trajectory was seriously affected by bullet drop after a comparatively short range—41 m (135 ft) of drop in the first 1,000 m (3,300 ft) of range. The long time of flight and curved trajectory strongly reduced the usefulness of the MK 108 against maneuvering targets like fighters; it was designed for use against bombers. Even against these, attacks had to be pressed home to close range (often, at just 200-300 meters), which was particularly challenging for fast fighters like the Me 262, which risked colliding with the target if their approach speed was too high."
