Green bullets not so green
CBS news (yes, that CBS news):
Army officials at Camp Edwards believed they were being eco-friendly when they started using a “green bullet” that contains no lead — a move meant to prevent polluting an aquifer beneath the base.
But six years later, after a million rounds have been fired at the base’s shooting ranges, new information suggests the green bullets may not be much better for the environment than the lead ones.
The bullets are made of nylon and tungsten. I recall reading that the copper bullets recently introduced (after jumping through various governmental hoops) were also supposed to be environmentally friendly and, as a bonus, provide more stopping power.
