From RtCW for dummies:

Now you can check it from there or test it by yourself, but the sniper rifle scoped to head is not an instant kill like it should be. The reason is that in the beginning you have 100hp, but at battle sense 3 you get +15 and from 4+ medics on your team you get +40hp so that brings it to 155hp.
So therefore I propose that the damage made by K43 or M1 Garand, while scoped to the head should be 200 hp, as it does not matter how much it is as long as it kills with one shot.
Also I propose that the bodyshot damage should be brought to 70 hp, as it was originally designed to kill with two shots (50hp).
