Rimfire ammunition is a type of cartridge that is commonly used in firearms. It is called “rimfire” because the firing pin strikes the rim of the base of the cartridge, which contains the primer. This causes the primer to ignite and ignite the gunpowder inside the cartridge, propelling the bullet out of the firearm’s barrel. The main difference between rimfire and regular ammunition (also known as centerfire ammunition) is how the primer is ignited.
In rimfire ammunition, the firing pin strikes the rim of the base of the cartridge, where the primer is located. The primer contains a small amount of explosive material that ignites the gunpowder and propels the bullet down the barrel.
Rimfire cartridges are typically small and used for low-powered firearms, such as small-caliber rifles. They are often used for target shooting, plinking, and small game hunting.
The most common rimfire cartridges include .22 Long Rifle, .17 HMR, and .22 WMR. These cartridges are widely available and relatively inexpensive compared to other types of ammunition.
