Originally loaded with a 40 gr bullet delivering velocities in the 2000 ft/s m/s range from a rifle barrel, .22 WMR is now loaded with bullet weights ranging from 50 gr at 1530 ft/s m/s to 30 gr at 2200 ft/s m/s.http://federalpremium.com/ammunition/rimfire/family/game-shok/game-shok/757 Federal Premium Ammunition - Rimfire federalpremium.com 2017-12-05 2017-12-05 https://web.archive.org/web/20171205194553/http://federalpremium.com/ammunition/rimfire/family/game-shok/game-shok/757 deadhttp://www.cci-ammunition.com/products/detail.aspx?use=1&loadNo=0059 CCI Ammunition - Product Detail www.cci-ammunition.com History The .22 WMR was introduced in 1959 by Winchester, but was not used by Winchester until the Winchester Model 61 slide rifle could be chambered for it in 1960.Barnes 1972, p.275, ".22 Winchester Magnum Rimfire". The first rifle to be offered in the new chambering was the Marlin Levermatic rifle in 1959, because its design was easily modified to accept the more powerful cartridge. By the time of the introduction of the Winchester 61, Smith & Wesson and Ruger had revolvers for it, and Savage had come out with the Model 24 and since late 2012, the Model 42, a more modern update than the 24, a .22/.410 rifle/shotgun combination gun. It was the only successful rimfire cartridge introduced in the 20th century.Cartridges of the World 10th Krause Publications Frank C. Barnes 2003 Stan Skinner 978-0-87349-605-6 Dimensions and loading The .22 WMR uses a larger case than the more popular .22 LR, both in diameter and length. The .22 WMR case is a lengthened version of the older .22 WRF and both of these cartridges have the bullet seated within the case, instead of using a heeled bullet as in the .22 LR. In the most common modern .22 WMR loadings using a 40 gr on bullet, the combination of more powder and higher sustained pressures gives velocities of 1875 ft/s m/s from a rifle and 1500 ft/s m/s from a handgun. A .22 WMR round will not fit into the chamber of a .22 LR firearm due to the greater length and width of the case dimensions. Although the bullet diameters are the same, the larger .22 WMR chamber does not support the smaller .22 LR cartridge. Firing the smaller .22 LR round in a .22 WMR chamber results in swollen or split cartridge cases, high-pressure gas leakage from the rear of the chamber, and bullets striking the chamber throat out of alignment, which can result in injury to the shooter or bystander and which does result in poor ammunition performance. Gun makers offer .22 revolver models with cylinders chambered either in .22 LR or in .22 WMR and as convertible kits with both cylinders which allow the shooter to easily switch calibers on the same firearm. Uses Since the .22 WMR uses bullets comparable in weight to the .22 Long Rifle, but is considerably faster, it shoots flatter and farther and hits harder at all ranges. The same 40 gr on bullet from a .22 WMR at 100 yard still has 50% more kinetic energy than .22 LR at the muzzle. The .22 WMR provides improved penetration and more reliable expansion at longer ranges with expanding bullets.http://www.cci-ammunition.com/products/products.aspx CCI Ammunition - View All CCI Loads www.cci-ammunition.com If sighted in for maximum point blank range on a 3 in mm on high target, the 40 gr on .22 WMR has an effective range of nearly 125 yard. This makes the .22 WMR a short to medium-range varmint rifle and hunting rifle cartridge. The .22 WMR can kill small game such as rabbits, hares, groundhogs, prairie dogs, foxes, raccoons, opossums, and coyotes.December 2017 Firearms using .22 WMR It first appeared in the Marlin Model 57M Levermatic carbines in 1959, which was followed by the .22 WMR over .410 bore Savage Model 24 combination gun, followed by Winchester's own Model 61 and 275 pump-action rifles and Model 255 lever-action rifle. The Chiappa Double Badger combination gun also comes with a .22 WMR over .410 bore option. The Springfield Armory M6 Scout is also made in .22 Magnum over .410 bore.https://www.gunsamerica.com/digest/the-m6-springfield-scout-rifle/ Bring Back The M6 Scout Rifle by JON HODOWAY on MARCH 5, 2016http://www.oldjimbo.com/survival/v-shrake/m6.html https://web.archive.org/web/20210425223834/http://www.oldjimbo.com/survival/v-shrake/m6.html 2021-04-25 The M6 Survival System The Chiappa M6 Survival Gun is similar combination gun that comes with a 12 gauge or 20 gauge shotgun barrel over a .22 Magnum barrel.https://www.chiappafirearms.com/f.php?id=35 Chiappa Firearms - M6 www.chiappafirearms.com 2018-10-28 2019-03-11 https://web.archive.org/web/20190311051738/http://chiappafirearms.com/f.php?id=35 dead A number of single-shot and repeating rifles were offered in .22 WMR. The .22 WMR operates at pressures beyond what normal blowback actions typically handle, but the self-loading Jefferson Model 159 was introduced for the cartridge.

In 2014 Kel-Tec released the CMR-30, a PDW-style rifle chambered in .22 WMR with a 16" barrel and a 1:14 twist rate. It uses the same double stack 30-round magazine as the PMR-30. In 2018 Standard Manufacturing introduced an 8-round .22 WMR revolver at the Las Vegas Shot Show. The revolver was originally introduced as the Volleyfire. The gun has side-by-side barrels, and fires 2 rounds of .22 WMR (1 bullet per barrel) with every pull of the trigger. In 2019 the gun went into production and was renamed "Thunderstruck". In recent years, a few UK companies such as Guncraft Ltd have been making semi-automatic AR-15-style rifles chambered in 22 WMR, marketed to civilian shooters who, due to the UK's restrictive gun laws, do not have access to self-loading center-fire rifles. Guncraft 22 Magnum AR15 Review Pete Moore. GunMart. October 14, 2019. Ammunition thumb|From the left, .22 Short, .22 LR, .22 Winchester Magnum Rimfire, and .22 Hornet The .22 WMR is an enlarged, more powerful version of the much earlier .22 WRF. Despite frequent claims to the contrary, it cannot be safely used in any firearm except those specifically chambered for it. Even firearms chambered for the .22 WRF are not suitable; for one thing, the case lengths are different, and the fact that the cartridge fits into the chamber does not guarantee that using the wrong cartridge is either safe or effective.Barnes 1972, p.275, ".22 Winchester Rimfire (WRF)" The .22 WMR was for a time the most powerful rimfire round available; it even outperformed the .22 WCF. It has since been eclipsed in velocity and overall kinetic energy by the .17 Winchester Super Magnum. Commonly available in retail stores, the selection and availability of the .22 WMR nevertheless does not match the popular .22 Long Rifle. Furthermore, .22 WMR is typically much more expensive than .22 LR per round, though it is comparable to .17 HMR, which is much more similar in overall performance, and is less expensive than .22 caliber centerfire ammunition. Because many of the rifles that are chambered for the .22 WMR have tubular magazines, the bullet noses generally are flat or at least blunt to allow smooth feeding and reduce damage to the bullet. Sparano Vin The Complete Outdoors Encyclopedia St. Martin's Press New York 2000 978-0-312-26722-3 Although a pointed bullet in a rimfire cartridge will not contact the primer of the round in front of it (which is a hazard with centerfire cartridges in a tubular magazine), the manufacturer's stamp is in the middle of the base of a rimfire cartridge, and this may interfere with pointed metal bullets in a tube. However, Remington, CCI, and Hornady now produce bullet designs with 30 or 33 gr on polymer plastic ballistic tips that reduce the hazards of pointed ammunition in tubular magazines.http://www.remington.com/products/ammunition/rimfire/magnum_rimfire.asp 2008-06-17 Remington Magnum Rimfire: 22 Win Mag PR22M1 33-grain AccuTip-V Remington Arms Company, Inc. https://web.archive.org/web/20080530170242/http://www.remington.com/products/ammunition/rimfire/magnum_rimfire.asp 2008-05-30http://www.cci-ammunition.com/ballistics/rimfire.aspx CCI: Varmint 0073 22 Magnum RF V-MAX 30-grain poly-tip 2008-06-17 CCI https://web.archive.org/web/20080516032801/http://www.cci-ammunition.com/ballistics/rimfire.aspx 16 May 2008http://www.hornady.com/shop/?page=shop%2Fbrowse&category_id=9b26ee2729baf268e4ae1c61acde17cc https://web.archive.org/web/20090210190834/http://www.hornady.com/shop/?page=shop%2Fbrowse&category_id=9b26ee2729baf268e4ae1c61acde17cc 2009-02-10 Hornady: 22 WMR 30-grain V-MAX 2008-06-17 Hornady Manufacturing, Inc. Bullets for the .22 WMR are generally unlubricated lead with heavy copper plating, in either solid nose or hollow point style designed for small game hunting or pest control (varmint hunting). The limited selection of commercial ammunition for the .22 WMR has inspired specialist wildcatters to select the .22 WMR case for handloading high performance rimfire ammunition. Generally they load the wildcat cartridges with pointed bullets for the aerodynamic advantages, using the same bullets as those in .22 caliber centerfire cartridges. Though such bullets are generally heavier than standard .22 WMR, the sharp nose and tapered tail conserve energy better, delivering greater impact at longer ranges. Other wildcatters neck the .22 WMR down to smaller calibers, such as .20 (5 mm) and .17 (4.5 mm) or even smaller, in an attempt to get maximum velocity and the flattest possible trajectory. An example of such an experimental design is the Swedish 4.5×26mm MKR.
