Nontoxic Shot Regulations for Hunting Waterfowl and Coots in the U.S.
Current as of March 16, 2018
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.
Approved shot types
The shot types that are approved as nontoxic for waterfowl hunting in the U.S. are the following.
