The bullets from the scout seem to come from the lower right of the screen rather than the center(where the rifle is when you're zoomed in). This is usually not a problem, but on rare occasions such as you being able to see the top of the head of a guy behind a wall it makes a difference; it's nearly impossible to hit it (think 1 pixel leeway) because the angle of the rifle is not that of your view. So, could the bullet originate from the center of the screen while you're zoomed with a scout rifle? Slightly below the center would be most realistic, but then the problem would still be there.
lol So maybe you not hitting the guy behind the wall has more to do with screwed up hitboxes of the wall than the scout rifle?
I don't think walls can have screwed up hitboxes. Well, maybe the structure, but I was thinking of map-set walls... Okay, so the problem isn't the origin, it's the accuracy? I thought the scout rifle was pinpoint when crouched.
