Thats easy ok so.... First aim your crosshair (not the scope crosshair but the crosshair that is on like a AR when you arent using your sight_)at the guy you would like to shoot, then align the middle of the crosshair at his head or chest (Chest if DSR50 because come on DSR50 is gonna be a one hit k**l to the chest or most other snipers are usually a one hit k**l to the upper chest) Ok so align the middle of the crosshair to te guy you would want to shoot then quickly scope in and shoot, obvisouly hit the steady mode right when you scope in therefore causing it not to sway off of him. And then you should k**l him.
