When the bolt is operated by opening the lever, there can be a failure to extract the cartridge from the chamber, or a failure to eject the cartridge clear of the rifle. These failures usually are the result of the lever not being operated correctly, use of improper or damaged ammunition, or an accumulation of bullet lubricant or residue from firing in the chamber. From the foregoing, it is clear that the gun user must:
1. Always visually check the chamber after opening the bolt to eject a chambered cartridge. If the lever is not vigorously retracted when opening the bolt, the extracted cartridge can be 'ejected' into the magazine area, instead of outside the rifle.
2. Thoroughly clean the chamber and the extractor as often as necessary to prevent the accumulation of grease and dirt.
3. If an empty magazine is in the rifle when the lever is being operated to extract a cartridge, the cartridge may drop on top of the magazine. Then when the bolt goes forward, the cartridge will be chambered again! Always remove the magazine before clearing the chamber, and visually ensure that no cartridges remain in the gun.
