Legal Requirements When Selecting a Firearm for Hunting: What Federal and State Law Say

Last reviewed: October 5, 2026. This article is general information, not legal advice. Hunting rules change every season and differ by state, species and zone, so check your state wildlife agency's current regulations before you hunt.

Choosing a hunting firearm usually starts with practical questions: what are you hunting, how far will you shoot, what feels right in your hands. But before any of that, there are legal requirements when selecting a firearm for hunting, and getting them wrong can mean a fine, a lost licence, or worse.

Short answer: The legal requirements come from two levels. Federal law decides who may possess a firearm at all (18 U.S.C. § 922(g)) and sets method rules for migratory birds such as ducks and geese. Your state's wildlife agency decides which firearms, calibers, gauges and ammunition are legal for each species and season, and whether you must wear blaze orange. Check both before you buy or hunt.

Step 1: Make sure you can legally have a firearm

A hunting licence doesn't give anyone the right to possess a gun. Under federal law, 18 U.S.C. § 922(g), it's unlawful for several groups of people to possess a firearm or ammunition. In summary, they include people who:

• have been convicted of a crime punishable by more than one year in prison;
• are fugitives from justice;
• are unlawful users of, or addicted to, a controlled substance;
• have been adjudicated as a "mental defective" or committed to a mental institution;
• are in the US unlawfully, or (with exceptions) on a nonimmigrant visa;
• were dishonorably discharged from the Armed Forces;
• have renounced US citizenship;
• are subject to certain domestic violence protective orders; or
• have been convicted of a misdemeanor crime of domestic violence.

One recent development: on June 18, 2026, in United States v. Hemani, the Supreme Court held that prosecuting a regular marijuana user under § 922(g)(3) violated the Second Amendment in the circumstances of that case. The Court described its ruling as narrow, and the statute is still on the books, so don't treat it as a general green light. If any of these categories might apply to you, talk to a lawyer before you buy or carry a gun.

States can add their own restrictions, permit requirements and transport rules on top of federal law.

Step 2: Match the firearm to your state's legal methods

Wildlife agencies regulate how game may be taken. Rules commonly cover:

• Firearm type by species and season (for example, muzzleloader-only or shotgun-only seasons or zones).
• Minimum caliber or gauge, and whether rimfire is allowed.
• Ammunition, such as single-projectile, expanding or soft-point bullets for big game.
• Magazine capacity, especially for birds.
• Blaze orange (or blaze pink) clothing during firearm seasons.

Here are three examples, each checked against the state's official source.

Example: Minnesota

Minnesota Statutes § 97B.031 says a person may take big game with a firearm only if any rifle, shotgun or handgun is at least .22 caliber with centerfire ignition, it's loaded only with single-projectile ammunition, and the bullet has a soft point or is an expanding type. Smooth-bore muzzleloaders must be at least .45 caliber and rifled muzzleloaders at least .40. Firearms larger than 10 gauge are prohibited for any protected wild animal.

Minnesota § 97B.071 requires hunters and trappers during firearm deer seasons to wear blaze orange or blaze pink on the visible portion of the cap and outer clothing above the waist (excluding sleeves and gloves). Camouflage counts only if it's at least 50 percent blaze orange or pink within each square foot.

Example: Texas

Texas Parks and Wildlife says game animals and non-migratory game birds may be hunted with any legal firearm, except that rimfire ammunition of any caliber may not be used for white-tailed deer, mule deer, desert bighorn sheep or pronghorn. In the East Zone, shotguns are the only legal firearm for wild turkey. During muzzleloader deer seasons, only true muzzleloading firearms may be used. Pre-charged pneumatic air guns are allowed for some big game, but must fire a projectile of at least .30 caliber, among other conditions. On TPWD's public hunting lands, hunters must wear at least 400 square inches of hunter orange, including orange headwear, during firearm hunting periods.

Example: Pennsylvania

The Pennsylvania Game Commission says deer hunters statewide must wear at all times at least 250 square inches of fluorescent orange on the head, chest and back combined, visible from 360 degrees, during the firearms deer season. An orange hat and vest will satisfy the requirement. Pennsylvania also has separate archery and flintlock muzzleloader seasons, so the firearm you choose determines which seasons you can hunt.

Step 3: Check federal rules for ducks, geese and other migratory birds

If you hunt waterfowl, doves or other migratory game birds, federal regulations at 50 CFR 20.21 apply on top of state law:

• No rifles or pistols, and no shotgun larger than 10 gauge.
• Your shotgun must be plugged so it holds no more than three shells, with a one-piece filler that can't be removed without disassembling the gun (limited exceptions apply to special goose seasons).
• For ducks, geese, swans and coots, you may only use approved nontoxic shot types.

Common mistakes to avoid

• Assuming one state's rules apply in another. A rifle legal for deer in one state may be illegal in a shotgun zone next door.
• Using the wrong ammunition for the species, such as rimfire for deer or lead shot for ducks.
• Forgetting to plug your shotgun before waterfowl season.
• Skipping the orange. Many states require it during firearm seasons, and some have extra rules for blinds.
• Ignoring transport and land rules. Check how you may carry a firearm in your vehicle, on public land and across state lines. Remember that hunting on private land needs permission; some states mark no-trespassing boundaries with purple paint.

If you're interested in accessories, rules on suppressors vary by state. Texas allows them for hunting while other laws still apply; see our explainer on whether silencers are legal in Florida. Before you head out, it's also smart to leave a hunting plan with someone you trust. For the bigger picture, see why hunting laws were passed.
