thanks man i really apreciate the avice and ill do my best to keep it in mind and use it :)

U just have to keep moving, turn shoot. repeat... ;')
Thing is like training ground (underground place) when u keep making big circles.
U group them up in a big pack, when u then turn and spray and pray while aiming on the heads.
Most likely u already kill 99% with 1 mag alone, it is just importent that u get u head around their pathing.
