Compared with lead core, depleted uranium, tungsten ammunition core do not adversely affect groundwater. Soil containing lead stunted the growth of rye grass, but the plant was unaffected by soil containing tungsten. Scientists also exposed earthworms to soil containing the two metals. Studies stated that there was no abnormal growth while using tungsten ammunition core, the reproductive patterns were the same. But in the lead-contaminated soil, the plants got smaller, and didn't have any offspring and died out. Therefore, that’s the most important factor to replace lead cores by tungsten ammunition core. The Army wants ammunition that is less likely to cause environmental damage, an alternative to lead-core ammunition of tungsten ammunition core can’t pollute ground water and solve their cleanup headaches. Environment protection becomes more and more urgent and important to human beings.
Besides, lead-free ammunition cores are designed for explosive performance; great accuracy and total disruption make it ideal varmint rounds, with a tungsten-based ammunition core and a poly-tip to provide devastating performance at both short and extended distances. Those properties and military performance are superior to lead cores.
As the above advantages, tungsten ammunition cores are mainly adopted for the following applications:Small caliber ammunition
