Not Just a Camera Operator

Since I'm supplying one of the more dangerous props (namely a .308 Winchester Model 70 Police Sniper rifle) to one of our horror-flick productions, our Film Professor has appointed me Armorer for our production company. I'll be riding herd over all of our gun props and ensuring the actors don't look like doofuses while wielding them on camera. I don't know yet whether the chainsaw falls under my purview.
