This invention is an identifiable bullet having a slug made from an unsintered powdered metal composite core and a luminescent taggant mixture. The luminescent taggant mixture portion of the slug serves as an identifying agent that can be traced to the manufactured origin of the bullet thereby providing a means for matching the identity of a post-fired bullet with the identity of a pre-fired bullet manufacturer.
