is 22 mag the same as 22 wmr
The .22 Winchester Magnum Rimfire, also called .22 WMR, .22 Magnum, .22 MRF, or .22 Mag, is a rimfire cartridge. Originally loaded with a bullet weight of 40 grains (2.6 g) delivering velocities in the 2,000 feet per second (610 m/s) range from a rifle barrel, .22 WMR is now loaded with bullet weights ranging from 50 grains (3.2 g) at 1,530 feet per second (470 m/s) to 30 grains (1.9 g) at 2,200 feet per second (670 m/s). Accuracy around 1 MOA is achievable. Compared to the faster but lighter .17 HMR, the .22 WMR impacts targets with higher kinetic energy within its effective range, important for clean kills on larger small game such as coyote, albeit with a less flat-shooting bullet arc.
