THAT is what I don't get.. nobody can hit reliably with the 30mm!! It takes a lot of practice, and close ranges... And yet in reality the cannon ranges were longer than MG ranges! Bomber crews reported being hit by cannon by planes outside their gun range (albeit even if only outside guns range for a short moment). The 30mm was supposed to have LONG range, and with that long range could be fired with the standard gunsight, but in AH it's almost useless for anything past d200.
