What does the data stamp on a shotgun indicate?

The data stamp on a shotgun provides critical information about the gauge of the shotgun and the maximum shell length it can safely accommodate. This information is essential for hunters and shooters to select the correct ammunition for their firearm, ensuring safety and optimal performance. A shotgun's gauge indicates the bore diameter, while the maximum shell length specifies the lengths of shells that can be used without risking damage to the gun or injury to the shooter.

Having this data clearly marked helps prevent the use of improper ammunition, which could lead to malfunctions or accidents. Understanding this aspect of your firearm not only enhances safety but also improves your shooting experience by ensuring you are using the shotgun to its full potential.
