Ammunition Guide: Learn the Differences between Rimfire and Centerfire

What is the main difference between centerfire and rimfire ammunition, you ask? These are two different types of ammunition that are categorized by how the firing pin ignites the primer compound.

In rimfire ammo, the firing pin strikes the rim of the cartridge to fire the round. The primer compound is located inside the rim of the cartridge and is ignited when the firing pin punches the rim.

In contrast, centerfire ammo is fired when the firing pin strikes an externally visible primer in the center of the base of the cartridge.
