Abstract: A frangible bullet for use in training ranges as an alternative to live ammunition, which disintegrates upon impact with a target. The frangible bullet includes an elongated frangible core member fabricated from a thermoplastic polymer and at least one metal, the core member having a back end, an opposite tip end and a central portion therebetween, and having a core length between the back end and the tip end. The core member is jacketed in an outer jacket having a closed first end and an opposite opened second end, having a jacket length between the first end and second end, and defining a jacket chamber for complementarily receiving the core member therein. The core member fits inside the outer jacket such that the tip end of the frangible core member is exposed and impacts the target first, resulting in fragmentation of the core member and the outer jacket.
