  • Tagging of bullets with luminescent materials
    Publication number: 20020174794
    Abstract: 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.

  • Non-lead, environmentally safe projectiles and explosives containers
    Patent number: 6174494
    Abstract: A solid object having controlled frangibility, such as a bullet or a container for explosives, is made by combining two different metals in proportions calculated to achieve a desired density, without using lead. A wetting material is deposited on the base constituent which is made of a relative dense, hard material. The wetting material enhances the wettability of the base constituent with the binder constituent, which is lighter and softer than the base constituent.
    Type: Grant
