I have to agree with Greyflcn. If you aren't killing people with the gauss, you aren't using it right. If you are in point blank range with a gauss, you can still win, but just barely. You have to keep the center of the cof dead on the person and regardless of the spray, most of your shots will still connect. The only exception is the MCG, because he's doing the same thing but his bullets do much more damage.
I have about 5,000-6,000 gauss kills, so I think I can speak about the gauss in this thread, at least
