Learn More about .22 WMR

A .22 WMR History Lesson

The .22 Winchester Magnum Rimfire (WMR), often simply referred to as the .22 Magnum, was introduced by Winchester in 1959. Developed as a more powerful alternative to the .22 Long Rifle, the .22 WMR was designed to deliver better performance for small-game hunting and varmint control. Winchester released the ammunition first, with firearms manufacturers quickly following suit with revolvers and rifles chambered for the new cartridge.

Unlike earlier rimfire cartridges, the .22 WMR was engineered with a longer case and higher pressure, making it capable of significantly greater velocity and energy. This innovation filled a niche between traditional rimfires and centerfire cartridges, offering improved range and terminal performance without the recoil or expense associated with larger rounds.

Are .22 Magnum and .22 WMR the Same?

Yes, the terms “.22 Magnum” and “.22 WMR” refer to the same cartridge. “.22 Magnum” is a common shorthand used by shooters and manufacturers, while “.22 WMR” is the formal name: .22 Winchester Magnum Rimfire. There is no difference in dimensions or performance between the two designations.

It’s important to note that although .22 WMR and .22 LR share similar bullet diameters, they are not interchangeable. The .22 WMR has a longer case and is loaded to much higher pressures. Attempting to fire .22 LR in a .22 WMR chamber—or vice versa—is unsafe and not recommended.

What Is .22 WMR Good For?

The .22 WMR is widely appreciated for its balance of power, accuracy, and low recoil. Its applications range from hunting and target shooting to pest control and even self-defense.

  • Small-Game Hunting: The .22 WMR is ideal for hunting small animals like rabbits, squirrels, and raccoons. Its higher velocity compared to .22 LR ensures cleaner, more humane kills at greater distances.

  • Varmint Control: For farmers and rural property owners, the .22 WMR is effective at eliminating pests such as groundhogs, skunks, and coyotes. It offers sufficient penetration and expansion to take down medium-sized varmints with minimal overpenetration.

  • Target Shooting: While not as inexpensive as .22 LR, the .22 WMR is still an accessible round for recreational shooting. Its flat trajectory and mild recoil make plinking and informal target practice enjoyable.

  • Self-Defense: Though not traditionally a defensive cartridge, the .22 WMR has found use in compact revolvers and semi-automatic pistols marketed for concealed carry. Its performance with jacketed hollow point loads is comparable to some centerfire rounds, especially when recoil sensitivity is a concern.

How Affordable is the .22 WMR?

The .22 WMR is more expensive than .22 LR but remains affordable compared to most centerfire ammunition. A box of 50 rounds typically costs between $12 and $20, depending on the brand and bullet type. Specialty hunting or self-defense loads may cost more.

Compared to centerfire cartridges such as 9mm or .223 Remington, the .22 WMR offers a lower-cost option for shooters looking to maximize trigger time without sacrificing too much ballistic performance. This makes it especially appealing to budget-conscious hunters, recreational shooters, and new gun owners.

Firearms chambered in .22 WMR also come in a variety of price points. Bolt-action rifles, revolvers, and even semi-automatic pistols are available from manufacturers such as Ruger, Savage, Smith & Wesson, and Henry. Many shooters appreciate the versatility of these firearms, particularly in rural settings where pest control and small-game hunting are regular activities.
