A full choke is designed to constrict the shot column as it exits the barrel, which results in a tighter shot pattern compared to other types of chokes. This tightness is particularly beneficial for long-range shooting, as it helps to concentrate the shot into a smaller area.

In the context of shooting, when hunters or sport shooters aim for long distances, a tighter shot pattern is crucial for maintaining accuracy and ensuring that the shot is effective on the target. The constriction of a full choke minimizes the spread of the shot, which is advantageous when targeting animals or required precision in competitive shooting settings.

Other types of chokes, such as modified choke or improved cylinder, provide less constriction and therefore produce wider patterns, making them more suitable for different hunting scenarios or shorter ranges. A cylinder bore, characterized by no constriction, would have the widest spread and would not be effective for long-range shooting, as it disperses the shot too broadly.
