Be certain the primer of each cartridge is seated flush with, or below, the surface of the cartridge case base. A primer discharged by the closing of the bolt can result in a premature discharge of the cartridge with possible serious injury to the shooter and those nearby. Also, do not use exceptional force to close the bolt over a cartridge. If a cartridge does not chamber readily, check the bore and chamber to be certain they are free of obstructions. If they are clear, and the cartridge does not chamber readily, then check the cartridge to be certain it is the proper caliber, and of correct dimensions, for the rifle.
