History[edit]

6mm Flobert or .22 BB Cap ammo with Container

Frenchman Louis-Nicolas Flobert invented the first rimfire metallic cartridge in 1845. The 6mm Flobert cartridge consisted of a percussion cap with a bullet attached to the top.[5][6] These cartridges do not contain any powder, the only propellant substance contained in the cartridge is the percussion cap.[7] In Europe, the .22 BB Cap (introduced in 1845) and the slightly more powerful .22 CB Cap (introduced in 1888) are both called 6mm Flobert and are considered the same cartridge. These cartridges have a relatively low muzzle velocity of around 700 ft/s (213 m/s) to 800 ft/s (244 m/s).

Flobert also made what he called “parlor guns” for this cartridge, as these rifles and pistols were designed for target shooting in homes with a dedicated shooting parlor or shooting gallery.[8][9][10] 6mm Flobert Parlor pistols came into fashion in the mid-19th century; they typically featured heavy barrels. This cartridge was improved upon by Benjamin Houllier in 1846.

The next rimfire cartridge was the .22 Short, developed for Smith & Wesson‘s first revolver, in 1857; it used a longer rimfire case and 4 grains (260 mg) of black powder to fire a conical bullet. According to Berkeley R. Lewis, a firearms historian, this later Smith & Wesson cartridge was ‘essentially the same as Houllier’s 1846 patent’.[11] This led to the .22 Long in 1871, with the same bullet weight as the short but with a longer case and 5 grains (320 mg) of black powder. This was followed by the .22 Extra Long in 1880, with a case longer than the .22 Long and a heavier bullet.

American firearms manufacturer J. Stevens Arms & Tool Company introduced the .22 Long Rifle cartridge in 1887.[12] It combined the casing of the .22 Long with the 40-grain (2.6 g) bullet of the .22 Extra Long, giving it a longer overall length, a higher muzzle velocity and superior performance as a hunting and target round, rendering both the .22 Long and .22 Extra Long cartridges obsolete. The .22 LR uses a heeled bullet, which means that the bullet is the same diameter as the case, and has a narrower “heel” portion that fits in the case. It is one of the few cartridges that are accepted by a large variety of rifles and handguns.

.44 Henry rimfire cartridge

Larger rimfire calibers were used during the American Civil War in the Henry repeating rifle, the Spencer repeating rifle, the Ballard Rifle and the Frank Wesson carbine. While larger rimfire calibers were made, such as the .30 rimfire, .32 rimfire.38 rimfire .41 Short (for the Remington Model 95 derringer), the .44 Henry (for the Henry rifle and later used by the famous Winchester Model 1866), the .56-56 Spencer (for the Spencer rifle was the world’s first military metallic cartridge repeating rifle), up to the .58 Miller, the larger calibers were quickly replaced by centerfire versions, and today the .22 caliber rimfires are all that survive of these early rimfire cartridges.

The early 21st century has seen a revival in .17 caliber (4.5 mm) rimfire cartridges.[13] New and increasingly popular, the 17 HMR is based on a .22 WMR casing with a smaller formed neck which accepts a .17 bullet. The advantages of the 17 HMR over .22 WMR and other rimfire cartridges are its much flatter trajectory and its highly frangible hollow point bullets (often manufactured with plastic “ballistic tips” that improve the bullet’s external ballistics). The .17 HM2 (Hornady Mach 2) is based on the .22 Long Rifle and offers similar performance advantages over its parent cartridge, at a significantly higher cost. While .17 HM2 sells for about four times the cost of .22 Long Rifle ammunition, it is still significantly cheaper than most centerfire ammunition and somewhat cheaper than the .17 HMR. First shown at the 2013 SHOT Show, the .17 WSM uses the blank case from a .27 nail-gun necked down accommodate a .17 caliber bullet, resulting in substantially higher muzzle velocity and energy than the .17 HMR.

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.

 differences 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.

What caliber ammo is rimfire?

In addition to .22LR, other rimfire cartridges include .17 HMR.17 HM2, .17 WSM, .22 WMR, .22 Short, and other variations. You can find rimfire ammo in standard velocity or high velocity, with hollow point or JHP bullets, and different bullet weights. Besides recreational shooting, many shooters prefer rimfire cartridges for varmint hunting.
