i would love for the rear gunners in the 2 man planes to do little auto ack bursts and the il2's tail gun is 200 rounds of 50 cal ammo hardly a 20mm but it gets more dmg because its being fired into a plane moving into it I find the game actually models this speed difference and direction of the bullets Besides if your afraid of the auto ack hitting you with a single 30 cal every 3-4 bursts on a SLOW Near HELPLESS 2 man plane like a tbm etc then you need to work on your gunnery and merges.
