Explained: The Difference Between Rimfire and Centerfire

Rimfire and centerfire are two types of ammunition used in firearms. The main difference between the two is that rimfire ammunition is ignited by a primer located on the edge of the cartridge, while centerfire ammunition is ignited by a primer located in the center of the cartridge. Here’s a closer look at the key differences between these two types of ammunition:

Rimfire vs. Centerfire: How they work

As mentioned, the key difference between rimfire and centerfire ammunition is how the primer is located. In a rimfire cartridge, the primer is located on the edge of the case. When the firing pin strikes the edge of the case, it ignites the primer, which in turn ignites the powder.

In a centerfire cartridge, the primer is located in the center of the case. When the firing pin strikes the center of the case, it ignites the primer, which then ignites the powder.

Rimfire vs. Centerfire: Advantages and disadvantages

There are advantages and disadvantages to both rimfire and centerfire ammunition. Rimfire ammunition is typically less expensive than centerfire ammunition. Additionally, rimfire cartridges are usually smaller in size, making them ideal for use in smaller firearms such as pistols.

However, rimfire ammunition is not as powerful as centerfire ammunition. Additionally, because the primer is located on the edge of the case, rimfire ammunition is more likely to misfire than centerfire ammunition.

Centerfire ammunition is more expensive than rimfire ammunition, but it is also more powerful. Additionally, because the primer is located in the center of the case, centerfire ammunition is less likely to misfire than rimfire ammunition.
