Cannons 109E firing rate

Basically I never really look at the smoke trails as I do not care. I place the point where I want and then press button.

However, during high aspect ratios (basically from above) when I just let the target fly through my bullet stream I simply do not score hits or only very few with the MG. Hardly ever with the cannons. And often I am really close with the target filling basically almost the whole windshield.

I wonder if (like in old IL2) perhaps not all bullets are physically modelled but only some.

I really would like to have your experience with this kind of situation.

Anyhow both replies seem to confirm my observation.
