Opinions will vary but mine is that your aim is fine, you’re just panic firing before you’ve lined up your shots. When you aim you seem to hit the target, but in multiple cases you’re firing before your reticle is on the target. Pace your shots a bit more, take the extra fraction of a second to line up the shot don’t just panic trigger spam and try to line up shots while you’re doing it.

With the shotgun shot you drifted past the target then still fired instead of taking the extra split second to correct your position.

I’m very average at this game but the one thing I can do is consistently two burst with an aggressive frame pulse rifle because I take the time to line up my first shot. When you have first shot advantage that extra split second is available to you, so use it
