Gunnery totally strange

[Meek]

I have experienced this too, however, I'm quite ignorant about ballistics and WW2, so I'm especially ignorant about WW2-era ballistics.

I assumed it was because of the movement of the aircraft, it slightly "slinged" the bullets in the direction of the yaw, kind of like an incredibly weak (with effects visible at range) Wanted-esque bullet curving.

Dunno if it's realistic or not, that's just what I made of it.
