What is .22 WMR?
The .22 Winchester Magnum Rimfire (WMR) is a rimfire cartridge introduced by Winchester in 1959. It is also known as the .22 Magnum, .22 WMRF, .22 MRF, or .22 Mag. The .22 WMR is a more powerful evolution of the .22 Winchester Rimfire (WRF) and is designed for small game hunting and varmint control. While the .22 WRF can be fired in most .22 WMR firearms, the .22 WMR cannot be safely fired in a .22 WRF chamber due to its longer case and higher pressure. The .22 WMR is a popular choice among hunters and shooters due to its high velocities, flat trajectory, and effective range.
.22 Mag Specs & Velocity
The .22 Mag is a rimfire cartridge with a case diameter of 0.242 inches and an overall length of 1.055 inches. It has a rim diameter of 0.294 inches and a bullet diameter of 0.224 inches.
- Standard 40-grain FMJ or JHP loads have a muzzle velocity of approximately 1,875–1,910 feet per second (571–582 m/s) from a rifle barrel. Some premium loads can approach 2,000 fps (610 m/s).
- 30-grain V-MAX or JHP rounds reach around 2,200–2,250 fps (670–685 m/s).
- 50-grain bullets generally have a lower muzzle velocity, averaging 1,530–1,550 fps (466–472 m/s).
The .22 WMR offers a significant velocity and energy advantage over the .22 Long Rifle (LR), making it effective for small game, varmint control, and medium-sized predators at distances up to 125–150 yards.
Comparison to .22 LR
The .22 Long Rifle (LR) is a widely used rimfire cartridge that dates back to 1884. While it is affordable and effective for many applications, it has lower velocity, less energy, and a shorter effective range compared to the .22 WMR.
- A typical 40-grain .22 LR bullet has a velocity between 1,070–1,250 fps (326–381 m/s).
- In comparison, .22 WMR 40-grain bullets travel at 1,875–1,910 fps (571–582 m/s)—nearly double the velocity.
- The effective range of .22 LR is typically 50–75 yards, while .22 WMR can be effective at 125–150 yards.
The .22 LR remains the most affordable and widely available rimfire cartridge, but for hunters and varmint control, the .22 WMR offers significantly greater stopping power and range.
