What does California's nonlead ammunition law actually say?
Fish & Game Code §3004.5 requires nonlead ammunition — defined in the statute as ammunition "in which there is no lead content, excluding the presence of trace amounts of lead" — when "taking all wildlife, including game mammals, exotic game mammals, game birds, nongame birds, and nongame mammals, with any firearm." CDFW states plainly that this requirement has been in full effect statewide since July 1, 2019. Read narrowly, the operative phrase is "with any firearm" — the rule is written around the weapon, not the species or the land you're hunting on.
| Question | Answer | Citation |
|---|---|---|
| Does it require nonlead ammo for firearm hunting? | Yes, statewide, since July 1, 2019 | Fish & Game Code §3004.5 |
| Does it require nonlead pellets/slugs for air rifle hunting? | No — pellet rifles aren't "firearms" under state law | CDFW FAQ; Penal Code §16520(a) |
| Does CDFW still recommend nonlead for air rifles? | Yes, it's encouraged for small game, not required | CDFW — Nonlead Ammunition in California |
| Where does it apply? | Anywhere in California, public or private land | Fish & Game Code §3004.5 |
| Any exceptions? | Government duties; temporary caliber-specific supply shortages (condor range excluded even then) | Fish & Game Code §3004.5 |
Does this apply to air rifles?
This matters directly for airgun hunters in California: I hunt rabbits, doves, and pests with an FX Impact M4 running lead ACE FRAG slugs, which is consistent with what CDFW's own FAQ describes as legal. If you'd rather hunt with a nonlead slug anyway, nothing about that FAQ stops you — it just means the choice is yours to make, not the state's to require, for airgun hunting specifically. See California airgun hunting laws for the rest of what's authorized for air rifles in the state, separate from this ammunition-material question.
What counts as "nonlead" ammunition?
CDFW certifies ammunition at or below a threshold of 1% lead content, and copper or copper-alloy bullets are the most common commercially available nonlead option for centerfire hunting rounds. Manufacturers submit specific loads for certification, and CDFW keeps a running certified list rather than blanket-approving every product marketed as "lead-free." If you hunt with a firearm in California, check the current certified list for your specific caliber and load before the season, since products are added and occasionally removed.
Who's exempt, and what about shortages?
The statute carves out government employees and agents acting in their official duties, and it allows a temporary suspension of the nonlead requirement for a specific caliber if nonlead ammunition in that caliber becomes commercially unavailable because of unrelated federal restrictions on armor-piercing ammunition. Even then, the law is specific that nonlead ammunition stays mandatory within the range of the California condor, reflecting the lead-poisoning concern that drove the original legislation. None of these exceptions touch the airgun question above — they're about firearm ammunition supply, not about whether pellet guns are covered in the first place.
Why California did this in the first place
The nonlead requirement exists primarily because of lead's toxicity to scavenging wildlife, most famously the endangered California condor, which can be poisoned by ingesting lead fragments left in gut piles and unretrieved carcasses. That's also why the condor-range exception inside the shortage provision runs the opposite direction from what you might expect — nonlead stays required there specifically, even if a caliber-wide shortage temporarily loosens the rule everywhere else.
What this means for a firearm hunter in California
- Check your ammunition against CDFW's certified nonlead list before any firearm hunt, not just once when you first bought it — brands and specific loads do change.
- Copper or copper-alloy hunting bullets from major ammunition makers are the standard nonlead choice for centerfire rifle hunting.
- The rule follows the weapon, not the species — it's the same requirement whether you're taking deer, ground squirrels, or upland birds with a firearm.
Good fit
- Firearm hunters who verify their specific load against CDFW's current certified nonlead list before the season
- Air rifle hunters who understand lead pellets and slugs remain legal, per CDFW's own FAQ, while nonlead stays merely encouraged
- Anyone hunting near California condor range, where the practical and ethical case for nonlead is strongest regardless of the legal minimum
Look elsewhere
- Assuming any "lead-free" marketed product is automatically CDFW-certified without checking the list
- Assuming a rule that applies to firearms automatically extends to air rifles without reading CDFW's own FAQ on the question
- Treating this page as legal advice rather than a starting point — confirm with CDFW directly, especially on land with its own posted rules
Verdict
If you're hunting with a firearm in California, nonlead ammunition has been a hard statewide requirement since 2019 — check the certified list and don't assume a box labeled "lead-free" automatically qualifies. If you're hunting with an air rifle, CDFW's own FAQ is direct that pellet guns aren't firearms under state law, so the nonlead requirement doesn't legally reach you, even though CDFW encourages it. Either way, this is a rule written and interpreted by CDFW, so when in doubt on a specific property or a specific load, ask CDFW directly rather than relying on any single web page, including this one.
FAQ
What is California's nonlead ammunition law?
Fish & Game Code §3004.5 requires nonlead ammunition — defined as ammunition with no lead content beyond trace amounts — when taking any wildlife, including game mammals, game birds, nongame birds, and nongame mammals, with a firearm anywhere in California. CDFW states the requirement has been in full statewide effect since July 1, 2019.
Does the nonlead ammunition law apply to air rifles?
No. CDFW's own published FAQ directly addresses this: "Since pellet rifles are not considered firearms, the use of lead projectiles in pellet rifles is not prohibited." California's Penal Code §16520(a) defines "firearm" as a device that expels a projectile "by the force of an explosion or other form of combustion," which excludes air-powered pellet and slug guns. CDFW does encourage nonlead ammunition for small game hunting with an air rifle, but it isn't a legal requirement the way it is for firearms.
Is this the same rule as the ban on lead fishing weights?
No, they're separate rules covering separate activities. This page covers Fish & Game Code §3004.5, which governs ammunition used to take wildlife with a firearm. Lead fishing tackle is regulated under different, narrower rules that apply only in specific waters, not statewide.
What counts as "nonlead" ammunition in California?
Ammunition at or below a certified nonlead threshold of 1% lead content by CDFW's standard. Copper and copper-alloy hunting bullets are the most common commercially available nonlead centerfire option, and CDFW maintains a certified nonlead ammunition list, built in part from products manufacturers have submitted and had approved.
Does the nonlead rule apply on private land, or just public land?
It applies anywhere in California, public or private land alike, whenever you're taking wildlife with a firearm. This is a statewide hunting-method rule tied to the act of taking wildlife, not a land-management restriction limited to specific properties.
Are there any exceptions to the nonlead requirement?
A narrow few. Government employees and agents performing official duties are exempt, and the law allows temporary suspensions for a specific caliber if nonlead ammunition in that caliber becomes commercially unavailable due to unrelated federal restrictions on armor-piercing ammunition. Even during a suspension, nonlead ammunition stays mandatory within the California condor's range.
If lead pellets are legal for air rifle hunting, should you still use nonlead?
CDFW encourages it for small game hunting generally, and it's worth considering if you hunt near condor range or simply want one less thing to think about as rules evolve. But as of the current statute and CDFW's own FAQ, it isn't a legal requirement for air rifle hunters the way it is for firearm hunters — verify directly with CDFW before assuming that hasn't changed, especially if you hunt on a specific wildlife area or refuge that may set its own stricter rule.
What happens if you use lead ammunition with a firearm where nonlead is required?
It's a violation of Fish & Game Code §3004.5, separate from any other wildlife violation for the same hunt. Confirm your ammunition is CDFW-certified nonlead before a firearm hunt in California — check the current certified list directly, since specific loads are added and removed from it.
