I've never thought to test this in the game because my gunsight and dispersion testing offline is usually below 5k. And max range 600.
If you take your fighter out and auto level, then pull up the target. Eventually, depending on the gun, 30cal, 50cal, 13mm, 20mm and 30mm Mk108. Between 800 and 1200 the rounds will stop registering sprites on the target.
At higher altitudes do these ranges increase in the game? Have any of you leveled at 20k or 30k and tested against the target for max effective range?
The M4-37mm, Ns-37, BK3.7, Mk103 and BK5 have very long max ranges. It's the standard fair most players use in the game I'm asking about.
So has anyone tested max range on auto level 20k and above?
