22 Winchester Magnum Rimfire (WMR) Ammo

20 products in stock

The 22 Winchester Magnum Rimfire, usually shortened to 22 WMR or .22 Mag, has a longer case than the 22 LR and drives its bullets faster. That makes it a familiar choice for varmint-sized game and longer rimfire shots.

Bullet weights listed here run from 30 to 50 grain. CCI Maxi-Mag and GamePoint, Federal Game-Shok and V-Shok, Winchester Varmint HV and Dynapoint, Remington Premier and Speer Gold Dot Short Barrel cover the jacketed hollow point, soft point, polymer tip and full metal jacket styles, in boxes and bulk packs. As a rimfire, it has its primer in the rim of the case rather than the center.

Frequently Asked Questions

Can I shoot 22 LR in a 22 WMR firearm?

No. They are different cartridges, so use only the one stamped on your firearm.

What do JHP, JSP and polymer tip mean?

JHP is a jacketed hollow point and JSP a jacketed soft point, both made to expand. A polymer tip is a plastic insert in the nose that helps shape and expand the bullet.

Is 22 WMR the same as 22 Magnum?

Yes. 22 WMR, .22 Mag and .22 Magnum Rimfire all refer to the same cartridge.
