.22 WMR, often called .22 Magnum, is the hardest-hitting common rimfire cartridge. It shoots faster and flatter than .22 LR, making it a favorite for varmints, predators at close range and small game out to about 125 yards. At Gunners Outlet we carry .22 WMR ammunition from 30 to 40 grains, including hollow point and soft point loads from Winchester and CCI. Order online and we ship fast from our New Hampshire warehouse. Each product lists its price per round, so comparing value is simple.
About .22 WMR Ammunition
Winchester introduced the .22 Winchester Magnum Rimfire in 1959. It uses a longer, stronger case than .22 LR and drives bullets around 2,000 feet per second, roughly doubling the energy of a .22 LR at the muzzle.
Most .22 WMR loads weigh 30 to 40 grains. Lighter polymer-tipped bullets give the flattest trajectory for varmints, while 40 grain hollow points and jacketed soft points offer more penetration on larger pests. Some lighter loads, around 15 grains, are built for low recoil in small handguns.
.22 WMR and .22 LR are not interchangeable. A .22 LR cartridge in a .22 WMR chamber can split its case, so always use the cartridge your firearm is marked for. Buying .22 Magnum ammo by the box or in bulk keeps varmint season affordable.
Rifles and Handguns in .22 WMR
Popular .22 WMR rifles include the Savage 93, CZ 457 and Ruger American Rimfire, and many revolvers offer a .22 Magnum cylinder alongside .22 LR. From a short barrel, light loads designed for handguns perform best.
For pest control around farms and ranches, .22 WMR is often all you need inside about 125 yards.

Frequently Asked Questions
22 wmr vs 22lr: which is better?
.22 WMR is more powerful and flatter shooting, while .22 LR is cheaper and quieter. Choose .22 WMR for varmints and predators, .22 LR for plinking and training.
Can you shoot 22 lr in a 22 wmr?
No, you should not shoot .22 LR in a .22 WMR firearm. The smaller case fits loosely and can rupture, which is unsafe. Use only .22 WMR ammo in a .22 WMR gun.
What is the hardest hitting 22 mag ammo?
The hardest-hitting .22 Mag loads are usually 40 grain jacketed hollow points or soft points, which carry the most energy. For the flattest trajectory, a light polymer-tipped bullet is a better choice.
Is 22 wmr good for self defense?
.22 WMR offers more energy than .22 LR and can work for defense when recoil is a concern, though it is still on the low end. Test your load in your firearm for reliable function.
