I did a little test, and here is my results:
-It takes 2 hits to kill a person, friendly or non-friendly, and hitting it at a specific body part doesn't affect anything such as shooting someone in the head does not affect the amount of hits needed to kill
-There are 30 bullets in each clip, and you have 6 clips.
