6. If there is any reason to suspect that a bullet is obstructing the barrel, immediately unload the firearm and look through
the bore. It is not sufficient to merely look in the chamber. A bullet may be lodged some distance down the barrel where
it cannot easily be seen.
IF A BULLET IS IN THE BORE, DO NOT ATTEMPT TO SHOOT IT OUT BY USING ANOTHER CARTRIDGE OR BY
BLOWING IT OUT WITH A BLANK OR ONE FROM WHICH THE BULLET HAS BEEN REMOVED. SUCH TECHNIQUES CAN
GENERATE EXCESSIVE PRESSURE, WRECK THE FIREARM, AND CAUSE SERIOUS PERSONAL INJURY.
If the bullet can be removed with a cleaning rod, clean any unburned powder grains from the bore, chamber, and
mechanism before resuming shooting. If the bullet cannot be dislodged by tapping it with a cleaning rod, take the firearm
to a gunsmith.
7. Dirt, corrosion, or other foreign matter on a cartridge can impede complete chambering and may cause the cartridge
case to burst upon firing. The same is true of cartridges which are damaged or deformed.
8. Do not oil cartridges, and be sure to wipe the chamber clean of any oil or preservative before commencing to shoot. Oil
interferes with the friction between cartridge case and chamber wall that is necessary for safe functioning, and subjects
the firearm to stress similar to that imposed by excessive pressure.
9. Use lubricants sparingly on the moving parts of your firearm. Avoid excessive spraying of any aerosol gun care product,
especially where it may get on ammunition. All lubricants and aerosol spray lubricants in particular can penetrate
cartridge primers and cause misfires. Some highly penetrative lubricants can also migrate inside cartridge cases and
cause deterioration of the propellant powder; on firing, the powder may not ignite. If only the primer ignites, there is
danger that the bullet may become lodged in the barrel.
