What happens first inside a shotgun when it is fired?

When a shotgun is fired, the first action that occurs is the firing pin striking the primer. This impact ignites the primer, which then ignites the gunpowder inside the shell. The rapid combustion of the gunpowder generates gas and pressure that pushes the wad and shot down the barrel towards the target.

Understanding this sequence is crucial, as it establishes the fundamental operation of a shotgun and can influence a hunter's approach to safe handling and shooting techniques. The details of the firing mechanism are critical for ensuring that all safety protocols are followed during the shooting process.
