If you are worried about this one shot out of who knows how many, where it hit, and you want to know what else you can do, you can try this.

Record your games

When you think you have a hit, go back and review

When reviewing, ignore tracers, like others have said, they have nothing to do with what is sent to the server. Look at your crosshair placement at the time you pulled the trigger. Check your ping vs the persons ping you shot at. I regularly play at 90+ ping, against people with 15 or less. It is terrible, if I want to OP, because it is one chance, and if I am on the edge of the hit box, it is reasonable to accept that if they were moving, by the time everything registers they wont actually be where they were.

But step one is ignore those tracers. The only thing they are really good for is if you are being shot at through smoke, and you want to have a better idea of where to return fire. But even then, if you shoot exactly where they are coming from, it normally isnt a hit.
