Oh, shoot.

Silver bullet, I can understand, the kind rumored to be able to kill werewolves.  However, silver bullet seems to have morphed into magic bullet: "I'm sorry, I can't answer your question. I don't have a magic bullet."  A bullet made of silver is a possibility, I guess, but has there ever been a single instance of a magic bullet?  And what would it be capable of?  Maybe it could be fired into that crystal ball which no one ever possesses either.
