Hollow point ammunition is legal under federal law and in nearly every state, with no federal permit, tax stamp, or special license required to buy, own, or carry it. A single state broadly restricts civilian possession, a handful of cities regulate sale within their limits, and the usual federal rules about who can possess any ammunition apply the same way to hollow points as to target rounds. If you can lawfully buy a box of full metal jacket ammunition, you can almost always buy hollow points sitting next to it on the shelf.
Federal Law Does Not Restrict Hollow Points
No federal statute singles out hollow point ammunition. The Gun Control Act of 1968 treats it the same as any other standard commercial ammunition: legal to manufacture, import, sell, and possess.
The one federal ammunition category that is restricted is armor-piercing ammunition, defined at 18 U.S.C. § 921(a)(17)(B) to cover projectiles made entirely from tungsten alloys, steel, iron, brass, bronze, beryllium copper, or depleted uranium, along with fully jacketed handgun bullets whose jacket weight exceeds 25 percent of the projectile.1Office of the Law Revision Counsel. 18 USC 921 – Definitions Hollow points fall outside both parts of that definition. They use lead cores and copper jackets, and they are engineered to expand rather than penetrate armor. The ATF has confirmed this distinction in its enforcement framework.2Bureau of Alcohol, Tobacco, Firearms and Explosives.

Who Cannot Legally Possess Ammunition
Federal restrictions on ammunition target the buyer, not the bullet. Under 18 U.S.C. § 922(g), several categories of people cannot legally possess any ammunition, hollow point or otherwise:3Bureau of Alcohol, Tobacco, Firearms and Explosives. Identify Prohibited Persons
- Anyone convicted of a crime punishable by more than one year in prison
- Fugitives from justice
- People who use or are addicted to controlled substances
- Anyone adjudicated as mentally incompetent or committed to a mental institution
- Undocumented immigrants and most nonimmigrant visa holders
- Anyone who has renounced U.S. citizenship
- People subject to qualifying domestic violence restraining orders
- Anyone convicted of a misdemeanor domestic violence offense
A violation carries up to 15 years in federal prison.4Office of the Law Revision Counsel. 18 USC 924 – Penalties The ceiling was raised from 10 years by the Bipartisan Safer Communities Act in 2022.5Congress.gov. Bipartisan Safer Communities Act – Full Text
Age Rules for Buying Hollow Points
Federal law splits ammunition purchases by type. A licensed dealer cannot sell handgun ammunition to anyone under 21, or rifle and shotgun ammunition to anyone under 18.6Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Because many common hollow point loads are handgun calibers such as 9mm, .40 S&W, and .45 ACP, the 21-year minimum applies to most hollow point purchases at a retail counter.
Private sellers work under a different rule. Federal law prohibits a private seller from transferring handgun ammunition to anyone they know or have reason to believe is under 18, and imposes no federal age floor on private sales of rifle or shotgun ammunition.7Bureau of Alcohol, Tobacco, Firearms and Explosives. Minimum Age for Gun Sales and Transfers Some states set higher ages, so the federal floor is not always the whole picture.
A growing number of jurisdictions also require a background check or permit at the point of sale for any ammunition. These rules apply to hollow points and target rounds alike.
State and Local Restrictions
Most states treat hollow points identically to any other ammunition. According to the file, only one state broadly restricts civilian possession, and even there exceptions allow keeping the ammunition at home and transporting it for lawful purposes such as hunting and target shooting. A small number of cities have passed ordinances limiting the sale of expanding ammunition within city limits. Possession and use can remain legal even in cities where sale is not.
Whether a city can pass its own ammunition rules depends on state preemption law. Most states have preemption statutes that strip local governments of authority to regulate firearms and ammunition beyond what state law already provides. In those states, a city cannot independently ban hollow point sales or possession. A handful of states either lack preemption or leave enough room for local action that municipal ordinances still appear.
The practical takeaway: if you live in or pass through the northeastern United States, check local ammunition law before you buy or carry. That is where the tightest rules cluster. Elsewhere, hollow points sit on the shelf as ordinary consumer goods.
Traveling With Hollow Points
By Vehicle Across State Lines
The Firearm Owners Protection Act creates a federal safe harbor for transporting firearms and ammunition between two places where you can legally possess them. During transport, neither the firearm nor the ammunition can be readily accessible from the passenger compartment.8Office of the Law Revision Counsel. 18 USC 926A – Interstate Transportation of Firearms
In a vehicle with a trunk, both belong there. In an SUV, hatchback, or pickup, the ammunition must be in a locked container. The glove compartment and center console do not qualify.8Office of the Law Revision Counsel. 18 USC 926A – Interstate Transportation of Firearms
Courts have read FOPA’s safe passage narrowly. It shields continuous travel through a restrictive jurisdiction, not extended stops. A meal break is generally fine; an overnight stay in a jurisdiction that bans what you are carrying is a gamble the statute may not cover.
By Air
TSA bars ammunition from carry-on bags. Checked luggage is permitted, but the ammunition must be packed in a container made of fiber, wood, or metal, or kept in the original manufacturer’s packaging. Loose rounds in a suitcase will not pass inspection.9Transportation Security Administration. Ammunition – What Can I Bring Airlines often set their own quantity limits, so confirm with the carrier and declare the ammunition at check-in.
Across International Borders
Crossing an international border with ammunition is a different legal universe. A single forgotten round in a range bag can lead to arrest.
Mexico treats any ammunition possession by foreign nationals as a serious criminal offense. U.S. carry permits carry no legal effect there, and penalties include significant prison time.10Bureau of Alcohol, Tobacco, Firearms and Explosives. Traveling with Firearms
Canada allows non-residents 18 and older to bring in personal ammunition after declaring it at the border, completing a Non-Resident Firearm Declaration form, and paying a CAD $25 fee. Duty-free limits are 200 rounds for hunting and up to 1,500 rounds for recognized shooting competitions. Armor-piercing projectiles are barred from entry.11Canada Border Services Agency. Firearms and Weapons – Canadian Border Requirements
Hunting Regulations Often Require Expanding Bullets
In most states, hunting regulations require expanding ammunition (hollow points or soft points) for big game such as deer and elk. The rationale is humane harvest: an expanding bullet is more effective at producing a quick kill, which reduces the chance of a wounded animal escaping. Using full metal jacket ammunition for big game is a citable offense under most state wildlife codes and can jeopardize your hunting license.
Before hunting, read the state’s ammunition specifications closely. Rules often go beyond “expanding” and dictate minimum caliber, bullet weight, and sometimes specific construction.
Carrying Hollow Points for Self-Defense
Hollow points are the standard duty round for nearly every U.S. law enforcement agency, and they are the consensus choice among firearms instructors and defensive shooting professionals for civilian carry. Controlled expansion reduces the chance of over-penetration, which matters in home defense where family members may be in the next room or neighbors share a wall.
In the rare self-defense shooting that reaches trial, prosecutors have occasionally argued that carrying hollow points suggests intent to inflict maximum harm. Defense attorneys typically respond that hollow points are the standard ammunition carried by police departments across the country, chosen specifically to reduce collateral danger. Carrying what law enforcement carries is a straightforward position to defend.
The more consequential legal question is not the bullet but whether the use of deadly force was justified. If the shooting was legally justified, ammunition type is unlikely to change the outcome. If it was not, no ammunition choice will help.
