Small tip. For players that don't know when you use a sniper scope it puts a flashlight effect on you when you scope. This gives away your position and makes you an easy kill.
My fix for this was to simply stop using the scope. You literally lose zero accuracy (as far as the bullet itself) and with the SVD can even rush. I've been using it all day (add me @ Wuvluv) and been doing 40+ kills 2:1.
Anyways, sniping is much better overall if you just don't use a sniper scope. (I know it sounds stupid but atleast you can hide.)
