Approved Shot Types

The ban on the use of lead shot for hunting waterfowl was phased-in starting with the 1987-88 hunting season. The ban became nationwide in 1991. Nontoxic shot regulations apply only to waterfowl, defined as the family Anatidae (ducks, geese, [including brant], and swans) and coots. Nontoxic shot is defined as any shot type that does not cause sickness and death when ingested by migratory birds.
