If you are referring to “Buck” in the context of firearms or ammunition, it’s important to note that “Buck” typically refers to buckshot ammunition commonly used in shotguns.Buckshot is a type of shotgun ammunition that consists of multiple lead or steel pellets. The pellets are larger in size compared to birdshot and are designed for close-range shooting and hunting applications, particularly for deer and other medium to large game.

When referring to “Buck (case)” without further context, it is unclear if you are asking about a specific brand or model of shotgun shell or if you are referring to shotgun shells in general that are loaded with buckshot.

If you have any more specific information or questions about Buck shotgun shells or any other related topic, please provide additional details, and I’ll be happy to assist you further.
