The invention relates to a repeating weapon, especially to a repeating rifle, with a cartridge chamber and a bolt block, which contains a bolt that can move relative to the cartridge chamber and that can be locked by means of a locking device in a closed position. For improving the safety against elevated gas pressure, the cartridge chamber is embodied such that a cartridge can be pushed completely into the cartridge chamber and the cartridge chamber has a rear sealing surface sealing flush with the case bottom of the cartridge for contacting a breech block on a front bolt head of the bolt.
