I wasn't sure where to pose this question, so I figured that GW was as good a place as any. I have a scene in which a character has murdered someone, and there is a stand-off with the lone witness to the crime. The killer is the owner of a pawn shop, and he is standing behind the counter pointing a SKS-45 assault rifle at the witness. The witness is near the entrance and makes a break for the door. He is shot in the back just as he reaches the glass door by a single .45 cal round. My question is: From a distance of, say, 15 yards, do you think a bullet of that caliber, shot from an assault rifle, would stay lodged in the victim or would pierce through him and shatter the glass door directly in front of him?
