I was involved in a workplace shooting 41 years ago or so. Dude was pissed off at his wife over their impending divorce. Long story short, he gets himself drunk across the street, grabs his converted-to-.22 German Luger and walks into the store I worked in. Demands to know where is wife is, walks into the VPs office, puts the gun against the VPs forehead and pulls the trigger. Bullet hits his skull, travels around his head under the skin and exits out behind his ear. Knocked him out, but otherwise fine. Idiot finished himself off in front of me and another guy, but to the OP, bullets do some weird stuff sometimes.
