Anotations

Scope note:

Firearms in which the cartridge case of a fired shot is extracted and ejected and a fresh one loaded, but which require a squeeze of the trigger for each shot. To describe firearms which continue to fire without intermission as long as the trigger is pressed and the supply of ammunition lasts, use "automatic."
