Ask a QuestionProven Arms & Outfitters A bolt-action rifle requires the shooter to manually operate a bolt to load a round, eject the spent casing, and chamber the next round. In contrast, a semi-automatic rifle is designed to automatically eject the spent casing and chamber a new round with each pull of the trigger.
