What type of ammunition is commonly associated with higher pressure loads?

Centerfire ammunition is commonly associated with higher pressure loads due to its design. In centerfire cartridges, the primer is located at the center of the cartridge base, allowing for a more robust and reliable ignition of the powder charge. This configuration can handle higher pressures generated when the powder ignites, which is often necessary for large game hunting or long-range shooting where greater velocities and energies are desired.

Rimfire ammunition, on the other hand, typically uses a thinner case and the primer is built into the rim of the cartridge. This construction limits the amount of pressure these cartridges can withstand safely, resulting in lower overall loads compared to centerfire ammunition. While rimfire rounds are great for small game and target shooting, they do not reach the same pressure levels as centerfire options. Therefore, centerfire ammunition is the correct answer as it is more commonly associated with higher pressure loads.
