Lead-Free Ammunition: What Are the Regulations in California?

April 5, 2026

Quick Answer

In California, lead-free ammunition regulations have been in effect since 2019, requiring the use of non-lead projectiles for hunting certain species. This ban includes game birds, but does not apply to big game animals. Hunters must use ammunition with a minimum of 50% antimony content.

California Lead-Free Ammunition Regulations

The California Department of Fish and Wildlife (CDFW) has implemented regulations requiring the use of non-lead ammunition for hunting game birds, including waterfowl and upland game birds. This ban was enacted to protect California condors and other nontarget species from lead poisoning. Hunters must use non-lead ammunition when hunting these species, with some exceptions for traditional or tribal hunters.

Types of Lead-Free Ammunition

Monolithic bullets, made from a single piece of material, are one type of lead-free ammunition allowed for hunting in California. These bullets are designed to expand upon impact, reducing the risk of lead exposure. Copper or brass bullets are also permitted, but must meet specific standards for weight and expansion. Hunters should check with the CDFW to ensure their chosen ammunition meets the necessary requirements.

Alternative Ammunition Options

Hunters may choose from a variety of lead-free ammunition types, including copper, brass, or tungsten-based bullets. Some popular options include the Hornady SST and the Nosler Partition, both of which are designed for hunting game birds. When selecting ammunition, hunters should consider factors such as expansion, weight retention, and penetration to ensure effective hunting.
