Which shotgun action is self-loading?

The self-loading shotgun action is commonly referred to as a semi-automatic action. In this mechanism, the energy from firing a shell is used to cycle the action, eject the spent shell, and load a new shell into the chamber automatically. This allows for quicker follow-up shots compared to manual actions like pump-action or break-action shotguns. Popular examples include the Remington 1100 and the Benelli Super Black Eagle.
