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, espe-
cially where it may get on ammunition. All lubricants and aero-
sol 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
