A highly accurate projectile of death or destruction. Sir Walter Scott may have been the first to use the idea of a literal silver bullet in Lockhart (1808), “I have only hopes that he will be shot with a silver bullet.” The term caught on in the first half of the 1900s because the popular western hero of the radio program, The Lone Ranger, used a silver bullet. During the Korean War an antiaircraft shell that hit precisely on target was called “silver bullet.” By the late 1900s the term also was being used figuratively, as in, “We’re hoping our new software will be the silver bullet to put the company on the map.”
