Help with Stuka BK 37 tank attacking

[6./ZG26_5tuka]

Just digged threw my Stuka materials and was glad to fidnd a Bk3,7 manual among them.

 

If conversion setting in BoS don't include vertical convergence, the cannons should be set for 375 fixed vertical convergence by default.

Horizontal conversion as seen in the diagram below shows ~ 400m, which seems reasonable considering the pretty high vertical convergence used.

 

Just added it due to different opinions about what convergence to use for best results with the Stuka. With this I'm also taking my advise to use lower convergency  back and will try to use the historical setting instead.

What does it mean by "zweiter bei 1000 m " ?

 I like using those canons, the only problem is that so far i fired some 300 rounds and hit [Edited]

The line translates: "First intersection of the bullet trajectory with the line of sight at 375m, second at 1000m"

IIRC the vertical convergence in BoS is adjusted automatically, based on the horizontal convergence you set, although I'm not sure...  Maybe someone can confirm that ?

I think you are correct, I fiddled a bit with 110 convergence and it definitely had an impact on vertical conv as well

Correct. But without the figures for how they determine vertical convergence even the practical effectiveness of horizontal convergence is drawn in to question.

Ok so conversion can be set to any value outside the historical one without bad side effects. Good to have it confirmed, thx for testing.

 

Another note below the diagram states gun spread as 0.25% * shooting distance, means at 400m we have to consider max. 1m of gunspread (per gun). As those tests were most likely performed on a shooting range you can add a little on top of that due to turbulences, vibrations and recoil forces.
