Why use tungsten alloy shot?
High density, great hardness and resistance to high temperature make tungsten to be one
of the most sought-after materials for shotgun pellets in shooting history.The density of tungsten alloy is about 18g/cm3, only gold, platinum, and a few other rare metals have a similar density. So it is denser than any other shot material including lead, steel or bismuth. To understand how the density factors into performance, let's look at two spheres about the same size, a golf ball and a ping-pong ball.The golf ball is far denser and will fly farther and hit harder. Now reduce that size down two single No.4 pellets,one steel and the other a tungsten alloy. Get the picture? The tungsten will fly farther, hit harder and penetrate deeper. That means more birds, farther out, with fewer cripples. Another unique property of tungsten is that it is nontoxic;it isfrendly to enviorment,so it is safe for people to handle and work with.
