Heavy tungsten, for instance, can be mixed with different amounts of tin to make bullets that are either highly frangible or very dense and almost unbreakable. And thus, the search for true frangible bullets - fast, hard-hitting, but that will not penetrate several layers of sheetrock or...

The bullets are injection molded under pressure to produce a projectile of appropriate size and weight and comparable to similarly sized live ammunition. The consistency of the bullet is such that it is frangible and will break upon impact with any hard surface, such as sheet steel. 

Trainees have to exercise all the standard precautions though because although our bullets are frangible, they won t shatter unless they hit something harder than they are - at which point they virtually evaporate into dust. It isn t legal everywhere, but I ve taken deer and small game with our rounds.
