Which type of firearm requires manual loading after each shot?

A single-shot firearm requires manual loading after each shot, making it distinct from other types. This type of firearm has a chamber designed to hold only one round at a time. After firing, the shooter must manually open the action to eject the spent cartridge case and load a new round into the chamber before firing again.

This differs from a semi-automatic firearm, which automatically chambers the next round after a shot is fired, allowing for quicker follow-up shots without manual intervention. A revolver also allows for multiple shots without the need to reload after each shot, as it typically stores several rounds in a rotating cylinder. Meanwhile, a machine gun is capable of firing multiple rounds continuously as long as the trigger is held down, drawing ammunition from a belt or magazine without any manual loading after each round.
