What is .22 WMR?

The .22 Winchester Magnum Rimfire is a rimfire ammunition cartridge that was introduced in 1959 by the Winchester Repeating Arms Company. This cartridge was designed to offer increased performance compared to the more common .22 Long Rifle (LR) round while still retaining the convenience and affordability of rimfire ammunition. It is also referred to as the .22 Magnum or simply the .22 Mag.

22 WMR History and Development

The development of the .22 WMR cartridge can be traced back to the late 1950s when firearms manufacturers were exploring ways to improve the performance of rimfire ammunition. The goal was to create a cartridge that could deliver higher velocities and greater energy downrange while maintaining the compact and economical nature of rimfire rounds.

Winchester, a renowned firearms and ammunition company, took up the challenge and introduced the .22 WMR in 1959. The key innovation that set the .22 WMR apart from its predecessors was the use of a bottlenecked case. Unlike traditional rimfire cartridges with straight-walled cases, the .22 WMR featured a case with a bottleneck shape. This design allowed for increased powder capacity and more efficient ignition, resulting in higher velocities and improved ballistics.

.22 WMR Key Features and Specifications

Bottlenecked Case Design

The most distinctive feature of the .22 WMR is its bottlenecked case, which sets it apart from other rimfire cartridges like the .22 LR. This design enhances the cartridge's performance by providing more space for gunpowder, resulting in higher muzzle velocities and increased energy.

Bullet Variety

The .22 WMR is available in a wide range of bullet types and weights, making it suitable for various purposes. Common bullet types include hollow points, round-nose, and flat-nose designs, each offering specific advantages for different applications.

Rimfire Ignition

Like all rimfire cartridges, the .22 WMR is ignited by striking the rim of the cartridge case, where the priming compound is located. This ignition method is cost-effective and contributes to the affordability of the cartridge.


The .22 WMR is a versatile cartridge used for a variety of purposes, including target shooting, pest control, small game hunting, and even self-defense in some cases. Its flat trajectory and respectable energy make it suitable for shooting at longer distances compared to most other rimfire cartridges.

Muzzle Velocity

Depending on the specific load and bullet weight, the .22 WMR typically achieves muzzle velocities ranging from 1,600 to 2,300 feet per second (fps). This velocity range gives it excellent long-range capabilities, especially when compared to the .22 LR.


The .22 WMR is known for its accuracy, making it a popular choice among target shooters and varmint hunters. The combination of relatively high velocity and consistent ignition contributes to its impressive on-target performance.
