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. Semi-automatic rifles offer faster follow-up shots, while bolt-action rifles are typically more accurate due to their design.
