Don't forget timing the bullet to reach the destination. I noticed that in close combact, people run side to side, thus you must take in account of the time the bullet will reach the target. If the person is running to the right, I put my crosshair just a little ahead of the right ear (that way they run into your bullet

) . You'll have to experiment to see how much far you'll have to put your crosshairs. I noticed a lot during the game that people will completely expel a whole mag and miss me completely, probably cause their crosshair was on my left arm/trunk/feet while I was running right and vis versa.
