What should be done before loading a shotgun?

Before loading a shotgun, it is essential to match the gauge on the bottom of the shell to the shotgun's datastamp. This step ensures that the ammunition is suitable for the firearm you are using. Shotguns come in various gauges, and using the wrong gauge can lead to serious safety issues, such as misfires or even catastrophic failures, which can cause injury to the shooter or bystanders.

Matching the gauge helps to confirm compatibility between the shotgun and the ammunition. Each shotgun has a specified gauge, and using ammunition that does not correspond with this can compromise the functionality and safety of the firearm. Always ensuring that the ammunition matches the specifications is a critical best practice for safe handling of shotguns.
