From the NSSF:

he U.S. Court of Appeals for the District of Columbia today upheld the dismissal of the latest lawsuit brought by anti-hunting groups petitioning the Environmental Protection Agency (EPA) to issue regulations banning traditional ammunition with lead components. The refusal by the EPA to consider the petition was challenged by the anti-hunting petitioners in federal court in 2013.

Traditional ammunition represents 95 percent of the U.S. market and is the staple ammunition for target shooters, hunters and law enforcement, with more than 14 billion rounds sold annually.
