If you want to get multiple kills in close or even mid range combat pick a more appropriate weapon - Simple!!! Snipers are meant for long range engagements!!! Personally I think you should get obliterated if you try and use a sniper in CQC
You would whinge if the SMG's kept killing you in a couple of bullets right across the map or if a pistol killed in one shot any range too. Don't whinge because you are not using the weapons in the right way or situation.... You whinged because the fire rate of the bulldog but want a sniper rifle to act like it in close quarters - unbelievable!!!
