What characteristic defines an improved cylinder choke?

An improved cylinder choke is designed to provide a moderate spread of shot, which means it allows for a relatively wider shot pattern compared to other chokes, such as a full choke. This characteristic makes it ideal for shooting moving targets, as it provides a balance between spread and control.

The choke does not significantly tighten the shot pattern, as that would typically be the role of tighter chokes like modified or full chokes. It also isn't adjustable—most chokes, including the improved cylinder, are fixed and must be changed in order to alter shot constriction. Lastly, while an improved cylinder choke can handle slugs, it is not exclusively intended for that purpose; it is primarily used for shooting birdshot or buckshot at game birds and small game.

By understanding the function and design of an improved cylinder choke, hunters can make informed choices about their shotguns and the types of hunting scenarios they are most suited for.
