Inspect for unfired primers by looking down the primer flash tube of the open end of the cartridge case. See
Figure 10. Looking at the primer head of a percussion or a combination electric and percussion primer will not
reveal if it has been fired. The primer flash tube should look burned and dark. Bright colors indicate that the
flash tube has not been fired. Remove any unfired primers from the cartridge case using a primer firing fixture to
drive the unfired primers through and out of the case. See Figure 11. All unfired primers will be removed prior
to storing the cartridge cases in the designated storage area. All safety procedures must be followed when
removing unfired primers from the cartridge cases. Face shield, work gloves, and hearing protection will be worn
while performing the depriming operation. Once the artillery brass and steel cartridge cases have been certified to
be free of explosives, they can be packaged and stored in designated bins or storage areas. Store brass and certain
other metal in the area designated for the storage of valuable metal.
