I just ain't got time to be aiming for guys' heads. Actually these days I'm all about the blue sniper rifles. I have a Painted Sammuramat-C and a Silvered Caracas LR4 both with a higher rate of fire than my P&T and close to max stability. All you really need is that high rate of fire and high stability since all the sniper rifles (at least outside of the IB) kill with two shots to the body.
