Which type of ammunition is limited to low-pressure loads?

The correct choice is rimfire ammunition, which is primarily designed for low-pressure loads. This type of ammunition generates less pressure compared to centerfire, shotgun, and handgun ammunition. Rimfire cartridges typically use a softer metal to ignite the primer, which encircles the base of the cartridge. This design inherently limits the amount of pressure generated during firing.

The low-pressure characteristic of rimfire ammunition makes it suitable for small game hunting and target shooting, where less recoil and noise are advantageous. It’s also more economical and is widely used in .22 caliber firearms, which are popular among beginner shooters. This design characteristic allows for a more manageable shooting experience, especially for those who are new to firearms or for youth shooters.

Centerfire, shotgun, and handgun ammunition can all generate higher pressures due to their different ignition methods and construction. Centerfire ammunition, for example, has the primer located in the center of the cartridge base and can be loaded with higher powder charges for more powerful rounds. Shotgun shells are designed for shotguns and can contain a range of load pressures depending on the type of shot or slug used. Handgun ammunition also varies widely in power, typically exceeding the pressure limits of rimfire cartridges.
