Lead-free ammunition is growing in popularity as alternatives to lead-based bullets given the health risks that lead poses to humans Jason Williams Jersey , wildlife, and the environment. In standard ammunition rounds, lead is the major constituent of the projectile mass.
Lead bullet fragmentation
Fragmentation in current lead-based bullets is an outcome of their design; the aim is that the anterior part of the ammunition enlarges to double its original diameter. However, one effect of this enlargement is that tiny pieces of lead break off from the bullet's tip as it collides and moves through its target. Tiny particles of lead are left behind in the body of the hunted animal which can be ingested during consumption, either by humans or carnivorous animals. This has been one of the main factors leading to the endangerment of the California condor. The high deer population that is hunted within the condor range leaves large numbers or lead contaminated corpses, which has resulted in anywhere from 45 to 95 of the condor population testing positive for lead exposure.
