Which firing mechanism is most commonly used in high powered firearms?

The most commonly used firing mechanism in high-powered firearms is centerfire. Centerfire cartridges have a primer located in the center of the cartridge base, which allows for reliable ignition of the powder when struck by the firing pin. This design is favored in high-powered firearms due to its durability and ability to handle higher pressure loads, making it suitable for rifles and handguns that require significant stopping power.

Centerfire ammunition typically offers better performance compared to rimfire cartridges, particularly in terms of accuracy and power, which are crucial for high-powered applications. The design also allows for the use of a variety of bullet types and sizes, accommodating the diverse needs of shooters and hunters.

The other mechanisms and options, such as single action and double action, refer to the firing action of the firearm, which is distinct from the type of cartridge being utilized. Revolvers being mentioned specifically does not encompass the wide range of high-powered firearms available that are not revolvers, such as bolt-action or semi-automatic rifles that predominantly use centerfire cartridges.
