Schematic of a rimfire cartridge and its ignition
Rimfire ammunition refers to a type of metallic firearmcartridges. It is called rimfire because the firing pin of a gun strikes and crushes the base's rim to ignite the primer. Invented in 1845, by Louis-Nicolas Flobert, the first rimfire metallic cartridge was the .22 BB Cap (aka: 6mm Flobert) cartridge, which consisted of a percussion cap with a bullet attached to the top.[1][2] While many other different cartridge priming methods have been tried since the 19th century, only rimfire technology and centerfire technology survive today. The rimfire .22 Long Rifle cartridge, introduced in 1887, is by far the most common ammunition in the world today in terms of units sold.

It is called rimfire ammunition because the firing pin of a gun strikes and crushes the base's rim to ignite the primer. The rim of the rimfire cartridge is essentially an extended and widened percussion cap which contains the priming compound, while the cartridge case contains the propellant powder and the projectile (bullet).
Rimfire cartridges are limited to low pressures because they require a thin case so that the firing pin can crush the rim and ignite the primer. Event id 300 source microsoft office 14 alerts event. Rimfire cartridges of .44 caliber (actually .45 caliber) up to .56 caliber were once common when black powder was used as a propellant. However, modern rimfire cartridges use smokeless powder which generates much higher pressures and tend to be of .22 caliber (5.5 mm) or smaller.[3] The low pressures necessitated by the rimfire design mean that rimfire firearms can be very light and inexpensive, which has helped lead to the continuing popularity of these small-caliber cartridges. Rimfire cartridges are also typically inexpensive, primarily because of the inherent cost-efficiency of manufacturing the cartridges in large lots.

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.[4][5] These cartridges do not contain any powder, the only propellant substance contained in the cartridge is the percussion cap.[6] 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). https://raysupernal994.weebly.com/blog/spintop-scrabble-activation-code-full-version-software.
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.[7][8][9] 6mm Flobert Parlor pistols came into fashion in the mid-19th century; they typically featured heavy barrels.
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. 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.[10] 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.[11] 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.

Some .22 caliber rimfire cartridges are loaded with a small amount of #11 or #12 shot (about 1/15th ounce). This 'snake shot' is only marginally effective in close ranges, and is usually used for shooting snakes, rats or other small animals. It is also useful for shooting birds inside storage buildings as it will not penetrate walls or ceilings. At a distance of about 10 feet (3 m), which is about the maximum effective range, the pattern is about 8 inches (20 cm) in diameter from a standard rifle. Special smoothbore shotguns, such as the Marlin Model 25MG 'Garden Gun' can produce effective patterns out to 15 or 20 yards using .22 WMR shotshells, which hold 1/8 oz. of #11 or #12 shot contained in a plastic capsule.
Theory And Design Of Air Cushion Craft
Shotshells will not feed reliably in some magazine fed firearms, because of the unusual shape of some cartridges that are crimped closed at the case mouth, and the relatively fragile plastic tips of other designs. Shotshells will not produce sufficient power to cycle semiautomatic actions, because, unlike projectile ammunition, nothing forms to the lands and grooves of the barrel to create the pressure necessary to cycle the firearm's action.
The 9mm Flobert is a notable rimfire cartridge that is still in production in Europe, and is chambered by the Winchester Model 39 in the 1920s. This cartridge is primarily loaded with a small amount of shot, but can also fire a small ball, and are used in 'garden gun', which are miniature shotguns. Its power and range are very limited, making it suitable only for pest control.[11] An example of rare but modern 9 mm Flobert Rimfire among hunters in Europe is the 1.75' Brass Shotshell manufactured by Fiocchi in Lecco, Italy using a .25 oz shot of #8 shot with a velocity of 600 fps.[citation needed]
