Can I legally hunt ducks with a shotgun that has a 20-inch barrel?

April 5, 2026

Quick Answer

In the United States, duck hunting regulations vary by state, but generally, a shotgun with a 20-inch barrel is allowed for hunting waterfowl, including ducks. However, specific barrel length and gauge restrictions may apply in certain states or regions. It's essential to check with your local wildlife agency for specific regulations.

Federal and State Regulations

When it comes to hunting ducks with a shotgun, federal regulations set a minimum barrel length of 18 inches for shotguns with a total length of 40 inches or more. However, some states have more stringent requirements. For example, in California, the minimum barrel length for hunting waterfowl is 18 inches for shotguns with a total length of 26 inches or more. To ensure compliance, always check with your local wildlife agency for specific regulations in your area.

Choosing the Right Shotgun

When selecting a shotgun for duck hunting, consider the type of hunting you’ll be doing and the terrain you’ll be hunting in. For hunting in dense vegetation or at close range, a shotgun with a shorter barrel (18-20 inches) and a shorter length of pull (12-13 inches) may be preferred. This will allow for easier maneuverability and quicker follow-up shots. On the other hand, for hunting in open fields or at longer ranges, a shotgun with a longer barrel (24-26 inches) and a longer length of pull (14-15 inches) may be more effective.

Hunting Techniques

When hunting ducks in a puddle, consider using a camouflage blind or a decoy spread to attract birds. Use calls sparingly to avoid scaring birds away. When taking a shot, aim for the bird’s head or body, as these areas are more dense and will result in a quicker kill. Keep in mind that ducks can fly quickly, so be prepared to follow up with a second shot if necessary. Always follow local regulations and practice safe hunting techniques.
