What do we mean by SuperHardCast?
Our use of this term is intended to differentiate between what have commonly been called hard-cast bullets and our very special SuperHardCast bullets. Hand-cast by us from custom Hensley & Gibbs blocks, our low-antimony bullets possess superior hardening characteristics. Our hardening process takes our bullets to 25-Brinnell, without the brittleness so common to high-antimony alloys. This is an essential element in the production of proper castings intended for use against heavy game. High-antimony alloys are the standard in the industry due to their ability to achieve acceptable rejection rates from automatic casting machines and 20-Brinnell hardness without additional hardening. This is what characterizes the better commercial machine-cast bullets. However, achieving hardness with the brittleness of high antimony alloys is hard to justify when the game is heavy or possibly dangerous. By contrast, our SuperHardCast Hammerheads possess none of the brittleness of high-antimo y bullets,
