Let's look at some actual footage of people being shot in the back of the head with vintage military rifles. This is from a documentary on the Chinese civil war. Start watching around 8:10 (warning: graphic). Notice that being shot in the back of the head does not produce a violent back-and-to-the-left movement. Also, the blood and brain matter goes forward; none of it is being blown back to the rear.
