What is the maximum effective range of a shotgun using #9 shot?

The maximum effective range of a shotgun using #9 shot is typically around 100 feet. This type of shot is small and generally used for target shooting or hunting small birds, making it less effective at greater distances. Shot size #9 is designed to create a dense pattern at short ranges, but it does not possess enough energy to be effective beyond the stated distance. Shot size greatly impacts the effectiveness, and #9 in particular loses its energy and pattern integrity quickly as distance increases.

In this scenario, the choice indicating that the effective range is at least 600 feet is not accurate, as that greatly exceeds the practical use of #9 shot. Understanding the limitations of different shot sizes helps in selecting appropriate ammunition for hunting and ensures ethical and safe shooting practices.
