Turret/Canon reticle movement on PS4

When turning a Phalanx or main canon on a BT, the reticle and whole barrel/canon (how would u say, continues to move then swings back). You know exactly what I mean, you quickly turn to that one enemy off in the distance, but you're reticle and canon keeps moving then jerks back. Insignificant amount of movement, yet it throws me completely off. I've played all kinds of shooters, been in all the vehicles, I've got unbelievable accuracy. The kind that gets me accused of hacking. But my god, I can't aim with these guns, when the target's too far. I cannot hit it (when they frequently adjust). I understand that the BT canon is separate from the body, but it throws so much off. This is the only game that has heavy weaponry poorly attached to their base. Example, the NC vanguard, obviously a US tank. When that tank canon moves it should be smooth and come to a complete stop. ...Not jerk in the direction it was moving then swing back as if the Canon were loose and momentum effected it but it has rubber bands inside that bring it back.

Do you guys know what I'm talking about? Is there a way to fix this? Also, you can tell these phalanx turrets are top heavy because they sway when u move them, aren't they suppose to be attached...?
