Um no? The point of 2a72 was to reduce recoil forces exerted on the vehicle so that it can be mounted on things like btr82 and 4x4 wheeled
Then, accuracy is bad. If you have spread then the beaten area increases. Especially with high rate of fire that is inaccessible for a bushmaster. No idea why you’re so obsessed on accuracy stat
Kinda, not really. Accuracy is really just a byproduct of a simpler design as there is less that can effectively ever so slightly mess up your accuracy.
Also, historically speaking; they really only used the 2A42 in low fire mode.
Trans station of what I need to know?
Also, funny, I used that video on my thread about the gun and this was debunked…
Keep in mind what you see in the video is high firing rate, as you can see by the gun oscillation, smoke, and tracer pattern.
I’m not entirely sure, but attempting to translate things, but “sigma” (σ) != median.
1σ is ~68%, 2σ is 95% and 3σ is 99.7% which again are not equivalent to 50%.
Also to convert milliradians to dispersion; is distance in cm / distance in meters.
so;
Dispersion in (Mrad * 1000) / range in meters = dispersion in meters
so the APFSDS rounds at say 1000 meters, would be at most (e.g. 3σ) be within 0.8 meters (80cm) of one another.
So it’s not obvious, though the western rounds should be more accurate even without a specific table.
Also Current production US rounds claim “0.44 / 0.77” mrad maximum (?3σ?) dispersion.

You dont either, facts of the matter is there is a ton of footage showing how inaccurate the cannons are and very little footahe showing otherwise not to mention that like i mentioned sixteen times already, the 2a42 is a cheap gas operated system.
And going by actual data is impossible if no such thing exist, ive spent the last few days searching for a manual or technical sheet, and im out of luck ive hit up a few libraries to see if they had anything but i havent got a response.
That was the doctrine, but in actuality its highly unlikely, in ukraine both sides have been using the high rpm setting a ton
a picture is stupid, i can provide some footage which shows a relatively inaccurate example of the m242.
1:00 there is a bradley firing at a target 990 meters away.
Complains about the inaccuracy of a model in the game compared to other;
People agree but ask for sources and datas;
Refuses to provide real source and only provide few footages with no know informations about the conditions where the said equipments is used;
Wrangles instead of providing when asked for actual data;
Repeat.
Armament accuracy is something hard to Gaijin changes, you actually need some very specific information about the equipment, something I don’t think no one without direct accessibility to the equipment can provide.
Found something for the M242 (?XM811?, APFSDS)

Mean (of 10 simulations) Standard Deviation(of 10 simulations)|0.050| 0.040
there are not many sources simple as, not to mention accuracy is highly dependant on a ton of factors. there are some generalizations around and you can find the trial requirements for more modern vehicles. but you arent going to find some specific data on the bmp2 easily as a non russian speaker.
In this case, regarding the 2A42 30 mm autocannon should be referred to 3UBR10, 3UBR8 and 3UBR11, respectively AP-T, APDS-T and APDS FS-T.
finding any data on 3ubr11 perfomance on a bmp2m is nigh impossible.
i found this but im not able to read well
and im pretty sure it might be about 3ubr8 and accuracy
From what I could find, XM811 is a experimental 40 mm HEI-T round,
do you speak russian?
I’m not on my computer at the moment, in one hour I might be able to get on-line and I can check the document better, maybe translating it to you.
It’s not that one. Seems like the designations clash. Might have been renamed / predecessor to M919, considering it did replace the M791 APDS in service.

im not a native speaker but the little i understand seems to be talking about the accuracy of 3ubr8(presumably applies to 3ubr11 too) out of 2a42. though i dont understand anything besides a few terms so i would really appreciate if you looked into it later(if you want ofc)
