November 2007 Press Release From Department of Energy's Oak Ridge National Laboratory:
Materials—Ready, aim . . .
As the new hunting season begins, an Ohio-based company is introducing a high performance bullet based on technology developed at Oak Ridge National Laboratory. The new bullet promises more precision and superior terminal ballistics and is lead-free and safe for the environment. Recently licensed to WolfTech of Wakeman, Ohio, the technology is first being made available to muzzle-loading hunters as part of a high performance system sold by MDM in Vermont. The bullets' composition—mixtures of tungsten and other metals or alloys—make them ideal for high performance hunting and target applications. The products will also help answer demand for greener ammunition as lead bullets are being banned in some states. [Contact: Larisa M.

Ammunition - Getting The Lead Out Of Bullets - Tungsten-tin composite provides alternative for hunter
LEAD IS DENSE and ductile, has a low melting point, and is inexpensive, making it long prized for molding into ammunition. But it's also toxic to birds and other animals that ingest bullets and bullet fragments.
To address the need for less toxic ammunition with the same performance as lead bullets, researchers at Oak Ridge National Laboratory have now developed bullets made from a tungsten-tin composite material. ORNL has licensed the technology to WolfTech Manufacturing, Wakeman, Ohio, and the first bullets will be distributed by MDM Muzzleloaders, Maidstone, Vt...
