German WW2 Plane Armarment 7,92 - 88 mm and their Ammunition

Dose this help?

Spoiler


Sadly not at all, perhaps i wasnt specific enough.
I didnt mean accuracy in terms of how well its implemented, but rather how small the shot group is at different distances.
In game as defensive armarment its currently an absolut shotgun in game, just test it on any Me 210/410.
Google sayes at 100m 35x45mm deviation, but without source and the best i could find was 1 book where they give it an accuracy factor slightly better than an Fixed 7,92mm Mg 17, but thats like saying nothing and just 1 source.

I even have yet to find any german manual that gives any info on it, nor did i find any other books.

Does an HE shell without tracer exist for the MG 151/15?

@KillaKiwi we had a talk some time ago, where i saw for 15mm ammo, that the round was to be replaced by M.Gr. and we came to the conclusion that most likely it was an copy error, but looking at a document again, there actually was a 15mm M.Gr. desinged in 1944. It is under an incorrect designation, but the filler is designated as HA 41.
Regarding your Question, with exception to the H-Pzgr. there were no main service tracerless rounds. However there were multiple rounds, such as this 15mm M.Gr, 15mm Sprgr. (Sonder-Ausf.) as well as a 15mm Brgr.44 high capacity Incendary round, that propably never saw service among more experimental rounds.

For MG151/20, I think currently the MG151/20 AP’s penentration might got some issues
151

At 600m it should have ~15mm penetration, but now we only have 14mm at 500m

Well, historical penetration data plays no role in the game.

Calculated data is often wrong but getting it right is far too complex.

It’s also neither wrong nor right, because armor can differ by a huge margin so armor thickness is just another variable of many.

By the way, the game is applying a completely arbitrary muzzle jump and additional dispersion whenever the gun is mounted in a defensive turret (for some reason, this doesn’t apply to tank or naval turrets, even though they are practically the same).

So, rather than the gun’s inherent accuracy, I think we should look at how these guns behaved in their specific mounts and how effective were the different recoil buffers used at dampening vibrations? Because even handheld MG 131s were mounted with some sets of springs or friction brakes…

Does this massive discrepancy in accuracy make any sense?

Wow, that’s crazy. Why is the aiming point flying all over the place. That shouldn’t happen.

But it’s happening to all defensive guns. Maybe it was always the case and I just don’t remember.

But the accuracy of defensive guns in general seems to be atrocious.

Maybe a result from overbuffed damage of guns and now defensive guns are nerfed to not smite airplanes out of the sky all the time.

It seems it has always had some degree of bouncing, but not as exaggerated as it is now. Lately, it even starts bouncing when aiming at an angle without even firing (maybe wind effect?)

I found these documents with dispersion patterns for B-29 turrets though I’m still not sure how they compare to the dispersion of fixed .50 mounts.
