What choke is most commonly used for duck hunting?

The most commonly used choke for duck hunting is the improved or modified choke. This choke provides a balance between shot spread and density, which is ideal for the fast, fleeting nature of duck hunting. The improved or modified choke allows for a more controlled shot pattern, enabling hunters to effectively hit moving targets at medium ranges.

Furthermore, ducks often fly at unpredictable distances, and this choke helps hunters achieve greater accuracy without excessive spread. While a full choke might provide a tighter shot pattern, it's less forgiving for quick shots on ducks which can easily change direction. Conversely, an open choke may lead to insufficient shot coverage for effective hunting. Thus, the improved or modified choke is particularly suited for the conditions and behaviors typical of duck hunting, making it the preferred choice among many hunters.
