Bullet sometimes goes far off course from where it was aimed. What causes this?

@Collector321

This is the eternal mystery of the first person shooter. Although it's really no mystery at all. It's any one of a dozen different things. Most commonly, your connection to the server is compromised at exactly the wrong time and Respawn's error correction is trying to help. For better or worse, who can say?

Not sure about the video, but it looks as if the bullet landed where you put it, although it seemed to take an odd detour along the way. But that could just be my bad eyesight.
