Firstly, this gun can kill ANYTHING. :)
On average I can get 8-12 T-90s with the 1150 CM rnds. I attack any tank the same way, doesn't matter what model it is. In general, attack from behind, 35-55* dive, aim for the top rear part of the tank, fire between .7-.5nm from target, give it a 1-2sec burst, jink out.
Note: 35-55* dive. I prefer the higher end of that bracket because the 50 cals cant aim up high enough to engage you. down at the 35*, you might take some fire, and your engines are vulnerable.
A higher dive angle will keep your rnd dispersion tight, and the closer you are the higher your muzzle velocity. make sense?
Here is an example from my yt channel.
