Buy Rimfire Ammunition online, Rimfire ammunition is a type of firearm metallic cartridge whose primer is located within a hollow circumferential rim protruding from the base of its casing. When fired, the gun’s firing pin will strike and crush the rim against the edge of the barrel breech, sparking the primer compound within the rim, and in turn ignite the propellant within the case. Invented in 1845, by Louis-Nicolas Flobert, the first rimfire metallic cartridge was the .22 BB Cap (a.k.a. 6mm Flobert) cartridge, which consisted of a percussion cap with a bullet attached to the top. While many other different cartridge priming methods have been tried since the 19th century, only rimfire and the later centerfire cartridges survive to the present day with regular usages. The .22 Long Rifle rimfire cartridge, introduced in 1887, is by far the most common ammunition in the world today in terms of units sold.
When most people say rimfire ammo, they’re usually referring to .22 Long Rifle, but it’s more than that. Rimfire ammo is widely considered to be an inexpensive small-caliber cartridge most often used for target shooting, a recreational-type of shooting called plinking, or varmint hunting.
What is rimfire ammo?
If you want to get technical, though, it’s any cartridge in which the primer is the rim of the case. With the design, a firing pin can strike any part of the rim to set off the primer and discharge the round.
What is the difference between a centerfire and rimfire ammunition?
While rimfire ammo is typically associated with small-caliber cartridges, centerfire is pretty much everything else and it applies to handgun ammo, rifle ammunition, and even shotshells. The biggest tell, though, for centerfire ammo is on the rim of the case, there’s a small circle in the center. That’s the primer and it must be struck directly. Hence the name, centerfire. Besides how they’re designed to operate, there’s another big difference between centerfire and rimfire ammunition. A centerfire rifle or handgun casing can be reused, but a rimfire case cannot. That’s because you can replace the primer in a centerfire case.

In addition to .22LR, other rimfire cartridges include .17 HMR, .17 HM2, .17 WSM, .22 WMR, .22 Short, and other variations.
