Best .22 Magnum Ammo

The .22 Winchester Magnum Rimfire (WMR), commonly known as the .22 Magnum, delivers rimfire performance well beyond the standard .22 LR. Introduced by Winchester in 1959, this cartridge has carved out a unique niche by offering significant velocity gains and improved terminal performance while maintaining modest recoil and reasonable ammunition costs.

Shooters often select the .22 Magnum when they need more power than a .22 LR but less recoil than centerfire options. Its higher velocity and improved penetration make it particularly effective for varmint hunting and pest control out to 100 yards. While primarily known as a rifle cartridge, the .22 Magnum has gained popularity in defensive handguns due to its minimal recoil, enhanced penetration, and reduced muzzle flash compared to centerfire options. The cartridge offers 40-50% more velocity than .22 LR, resulting in flatter trajectories and improved terminal performance.
