Bullet scatter is easily modeled with bullet "damage bubbles". If I could just know what size they are in game. At 200 yards they should be 30 inches.
Here's how the Bf-109 looks in sight at 200 yards
- differences between a single point convergence (yellow) and a more spread out (still concentrated) pattern (red):
And same for He-111
You can see, if bullet "damage bubbles" are smaller than 30 inches, getting a good shot would be like finding a needle in a haystack, literally.
At more than 200 yards you might as well throw the bullets out the window.
