Back from some quick tests I just did.
This time I set up a FMB mission with 4 B-29 as "Target Drones" and a Bf110 / Hs 129 for me (both armed with BK 3.7).
Bf110:
Ordered the 4 B-29 to fly a straight path across the map with 400 km/h at 1000m altitude.
Convergence for cannons was set to my usual 400 meters (didnt test other convergences now).
According to Wikipedia the BK 3.7 used in the Ju87 had a muzzle velocity of 780 - 1170 m/s, so I estimated a rough 950m/s (const.) for this test.
For the projectile to cover 400m it takes ~0.42 seconds, where the B-29 covers ~50m. So I took my shots from ~350m distance, primarily aiming for the engines 2 and 3.
Result was the bullets going too low, no hits unless I aimed over the wing or when my aim was sluggish and I didn't keep the plane stable. I took about 30 to 40 shots.
In addition I discovered a pattern, every 3rd shot goes sligtly low but still low, the 2 shots in between go way low.
Hs 129:
Adjusting the bombers' speed to 300 km/h and after taking the moving system into account again, I took my shots from about 360m.
This time aiming for engines 1 and 4.
5 shots 4 dead or burning engines, with the sight right on the engine nacelles. I give that one missed shot to my sluggish aim again.
In total I did about 10 shots with the Hs 129, but it got clear early that the bullets went where I aimed.
I might do more testing when there is more time, but so far my first impression got confirmed.
I even think taking a moving system into the equasion with muzzle velocity, travel time and bla wouldn't be necessary, but hey.
Once time permits and I did more testing on this, I will report further results.
In the mean time, maybe someone else could try some testing too, so we get more results from more than just 1 person.
So far thx all, have a good evening !
