History of 22 WMR Ammo

Developed by Winchester in 1959, the .22 Winchester Magnum Rimfire (WMR) was a potent cartridge that was soon produced by Smith & Wesson and Ruger. Winchester produced their Model 61 rifle for the .22 WMR beginning in 1960, while Savage introduced its famous Model 24 – a combination rifle for .22 WMR and .410 in an over-under configuration.

At its most basic level, the 22 Winchester Magnum Rimfire is an enlarged version of the popular .22 Winchester Rimfire (WRF). Contrary to popular belief, the WMR cannot be used safely in weapons chambered for the 22 WRF – or any other caliber. The WMR was the most powerful rimfire round in the world for many years, outperforming the .22 Winchester Centerfire. However, that distinction today belongs to the .17 Winchester Super Magnum. Another attractive aspect of the 22 WMR round for shooters is that it’s widely available and reasonably priced.

Bullet Points: 22 WMR Ammo

The .22 Winchester Magnum Rimfire (WMR) was a potent cartridge developed by Winchester in 1959. Widely used and well liked, this powerful little cartridge had low recoil, modest report, and it devastated small game.
Many shooters often wonder the difference between .22 WMR vs. .22 Mag. The .22 Magnum is just another name for the .22 WMR, so there is no difference between the two names.
.22 WMR ammo earned a “one shot stop” rating of 42% according to police agency report studies – which means it was able to stop an attacker from continuing their attack. While this may not compare to more powerful rounds, it does validate the .22 WMR as a self-defense cartridge.
Rifles and pistols of all action types have been chambered for the .22 WMR, which is why .22 Mag ammo for sale can usually be found on the shelves of most ammunition retailers.
