Canadian Firearms Safety Course (CFSC) Practice Exam

The correct choice indicates commonly available cartridge types, with rim-fire and center-fire being the two most prevalent categories used in firearms.

Rim-fire cartridges are distinctive because their primer is located in the rim of the cartridge base. This design makes them typically simpler and cheaper to manufacture, resulting in common uses for small-caliber firearms, particularly .22 caliber rifles and pistols.

Center-fire cartridges, on the other hand, have their primer located at the center of the cartridge base. This design allows for more powerful and larger ammunition, which makes up the bulk of commercially available ammunition for handguns and rifles. Center-fire cartridges can be reloaded, adding to their popularity among shooting enthusiasts who prefer to customize their ammunition.

Other choices do not accurately reflect the categories of cartridges. Shotgun and blank cartridges refer to different classes of ammunition but do not represent types defined by their method of ignition. Similarly, pointed and hollow-point refer to bullet shapes and designs rather than the cartridges themselves. Lead and steel describe types of projectiles or materials used but again do not denote inherent types of cartridges.

Thus, the distinction of rim-fire and center-fire signifies the foundational categories of ammunition available for a wide range of firearms, making them correct and relevant in this context
