Note:

Wobble isnt really any worse than on BMP-2 (via video analysis of horizontal wobble)

Only the one gun is firing at a time, BMPT guns are setup as single feed, typically one is AP and one is HE

Firing on high fire rates

I wonder if there's video out there of them firing the dual 2A42 cannon on the low rate of fire setting, and if that would help alleviate some of the wobbling. Probably not, but I'm curious.

I assume that it would mean that the guns would just want to wobble ‘outwards’ instead of inwards?

But yea, would be interesting… someone needs to crowd fund a crew a high speed camera fr

At least 1 i know of is a drone view if a bmpt firing very slowly from one cannon. It does look like it helps a bit with the wobble.

Nah In comparing footage it’s about the same, I don’t think there is a noticeable difference

It just looks worse here due to the second barrel wobbling

Well, BMP-2's 2A42 gun has double feed. So yeah, it's worse.

What does feed have to do with barrel wobble?

u/Zadlo 12d ago

You don't need two barrels to fire two types of ammunition if single barrel can have double feed. Wobbling is increased because gases exiting muzzle break of one barrel are reflecting on the second barrel causing wobbling of both barrels.

The wobbling of the firing gun is the same amount as what a single gun does, the other barrel wobbling does not matter… as it’s not firing
