Final answer:
This answer explains the difference between centrefire and rimfire cartridges, including their primer location and ignition method. It also mentions the advantages and typical uses of centrefire and rimfire cartridges.
Step-by-step explanation:
The main difference between centrefire and rimfire cartridges lies in the location and design of the primer. In a centrefire cartridge, the primer is located in the center of the cartridge case base, while in a rimfire cartridge, the primer is distributed around the inside rim of the cartridge case base.
This difference affects the method of ignition. Centrefire cartridges use a separate primer that is struck by the firing pin to ignite the gunpowder, while rimfire cartridges have the primer distributed throughout the rim and are struck by the firing pin directly.
Centrefire cartridges are generally more reliable, versatile, and powerful than rimfire cartridges. They are commonly used in handguns, rifles, and shotguns, while rimfire cartridges are typically used in low-powered firearms such as small-caliber handguns and rifles.
