Don't think for a second that the rounds wiggle across the sky, a bullet flies relatively straight and true. This is because the bullet is made to rotate around it's own axis by the rifling of the barrel.
It doesn't wiggle across the sky, but rotate around it's own core so to speak.

research rifling and you'll probably understand... Just because it looks good on videos doesn't mean that's how it looks/behaves in real life...

I can see that all of you are contrary for the spinning tracers but i think u are misunderstanding me...i didn't say that the tracer must go zig zag! i've only said that is spinning..like u are sayng..and it's true maybe in the photo there the tracers is to whagy..but it get's close but look here min 2 06..
even if the guncame shakes i don't know that gives all that effect to the tracers but nowne didn't answered me...why in game to the tempest for example they have that zig zag smoke tracer??
