Mig-3 has good armament. I often fly the 109-F, and Zero (the 2M not the 5M) and do get kills in them using just the 7mm. You just have to go for the soft kill. Rudders, elevators, flaps, wing tips, ect. are weak and vulnerable to the rifle caliber rounds.
Take a D3A in offline mode and blast those drones, and tell me that the rifle caliber round can't do some damage.
[OLD_DUFFER] You young kids and your cannon rounds. Spraying 'em like water through a hose. One hit is all 'ya could hope for with that nonsence. Marksmanship, thats what you kids need. When your cannons run dry 'ya run home, like 'yer momma was calling. Can't stick it out.
"Waa..waa I got's me no cannons. I cant kill anything instantly. Waa..waa."
