Think is simple to explain, and try out yourself.
Get the shotgun, and get to the point where u reload after every shot, now aim straight down, and fire while you're jumping, and do that a couple of times, a lot of times, it will fire to the side, and not down at all, if needed, I'll post a video, it happens all the time when I try.
Also, In CTF B2B or something like that, the bridges come up only half way, what settings do I change to correct that?
Edit: I have a Savage card, great... >_>
