Noting that casting one's own ammo is becoming a dying art, and that this might mean the extinction of silver bullets, this article describes the process required for casting your own werewolf-slayers:
To create the mold, I first had to construct a bit. I used a lathe to turn a steel rod into a bulletlike shape, then used a milling machine to cut away a quarter-circle wedge of the rod, leaving a sharp cutting edge. Basically I had built a router bit shaped like a bullet. (I've fabricated bits like this freehand with a file; which works fine, it just takes longer. Much longer.) After using the bit to machine the graphite bullet mold, I used an electrically heated graphite crucible to pour in 0.999 fine liquid silver at about 2,000*F, which is 230*F above its melting point. The mold must be preheated with a blowtorch to keep the silver from solidifying before it fills the whole cavity. One of the benefits of using graphite is that it keeps the silver from oxidizing, so bullets come out bright and shiny.
