Rim-fire or Center-fire?
The location of the primer tells you if a cartridge
is rimfire or centerfire. Generally, center-fire cartridges are more powerful
than rim-fire cartridges.
The
center-fire cartridge has a primer located in the center of the base.
The
rim-fire cartridge has no noticeable primer. Instead, the priming compound
is placed and spun into the case rim. When the rim is struck by the
firing pin, the priming compound explodes, igniting the powder.
