Best shotgun gauge for duck hunting in Oregon?

May 8, 2026

Quick Answer

For duck hunting in Oregon, a 12-gauge shotgun is the preferred choice due to its balanced power and versatility, although 20-gauge shotguns can be effective for smaller waterfowl. The 12-gauge's broad capabilities make it suitable for various hunting situations.

Choosing the Right Shotgun

When selecting a shotgun for duck hunting in Oregon, consider the type of hunting you will be doing. For example, if you plan to hunt in dense marshes or woods, a 12-gauge shotgun with 26- or 28-inch barrel length and a choke of improved cylinder (IC) or modified (M) is ideal. This setup will allow for effective shot placement and reduced pellet spread.

Shotshell Selection

For hunting in Oregon’s Pacific flyway, a 12-gauge shotgun should be loaded with 3-inch, high-brass, No. 2 or No. 4 steel shotgun shells. These sizes provide the right balance between pellet mass and spread, making them suitable for teal season as well as larger waterfowl species. When hunting in areas with dense vegetation, consider using No. 2 steel shot for improved penetration.
