Heli artilery

Hi everyone, I need some advice on how to properly use helicopter artillery. I just unlocked the new Mi-28NM and equipped it with S-8 rockets, because in top tier battles I can’t really do anything without something decent.

If I understand the theory correctly: I select the S-8 rockets, aim my HUD circle at the crosshair, and when it’s centered, I fire.

The problem is that the rockets fly in the right direction, but they never actually hit the target, and I don’t know what I’m doing wrong.
