22 WMR vs. 22 LR Comparison

22 WMR vs 22 LR Comparison

Hey all, we here at True Shot Academy are going to compare the .22 WMR to the .22 LR today. These two rimfire cartridges are exceptionally popular with a wide range of shooters and are employed for many use cases. We are going to explore many of the traits and features of these two cartridges as we comparing and contrasting them. Without further ado, let’s compare the .22 WMR and .22 LR cartridges.

.22 LR (.22 Long Rifle)

Originating in 1887, the .22 LR quickly rose to prominence, becoming a favored choice for a variety of shooting activities, including small game hunting and recreational shooting. The cartridge was derived from the earlier .22 Long cartridge and improved upon the performance and reliability of its predecessor. Notably, the .22 LR is capable of being utilized in a wide range of rifles, revolvers, and pistols, specifically those of the semi-automatic variety. This is due to the fact that .22 LR loadings operate at higher velocities and are capable of reliably cycling bolts and slides, a trait not possessed by the .22 Long. Since its introduction, the cartridge has been used for everything from training, competition, small game hunting, and even self-defense in some cases.

.22 WMR (.22 Winchester Magnum Rimfire)

The .22 WMR entered the ammunition scene much in 1959 with the promise of enhanced performance and power, becoming a go-to for many shooting enthusiasts and hunters alike. This newer, more potent rimfire cartridge was developed by Winchester and was first utilized by the Marlin Levermatic rifle in 1959. The cartridge is noticeably larger than its .22 LR counterpart, making it impossible to accidentally chamber a magnum round in a smaller chamber. Like the .22 LR, the .22 WMR is utilized in a wide range of firearms in both pistol and rifle form. Notably, the round’s high velocities make it well-suited for use in semi-automatic firearms as it can reliably cycle slides and bolts in these firearms. The .22 WMR is often used for various use cases such as hunting small to medium-sized game, varmint hunting, and target shooting. Purchase .22 LR Ammo

Is .22 WMR Interchangeable with .22 LR?

The two cartridges are quite different and feature different dimensions. Due to these dimensional differences, .22 WMR ammo will not fit into a firearm intended for use with .22 LR ammunition. While .22 WMR chambers are larger and can physically fit some smaller calibers, this practice is not always recommended. In the firearms world, there are some examples of firearms which are capable of accepting both .22 LR and .22 WMR ammo. A notable example is the convertible model of the Ruger Single-Six revolver as it features a .22” bore and interchangeable cylinders for either .22 LR and .22 WMR. Generally speaking, minus some exceptions, the two cartridges should be viewed as incompatible and not interchangeable. It's always a good practice to be aware of your firearm’s intended chambering. Doing so will ensure one acquires appropriate ammunition.

Is .22 WMR the Same as .22 Magnum?

Yes, the .22 WMR is the same cartridge as the .22 Magnum. The “WMR” in .22 WMR stands for “Winchester Magnum Rimfire,” denoting its magnum status. These two designations are simply different names for the same cartridge. Shooters will be able to employ both .22 WMR and .22 Magnum/.22 Mag marked ammunition interchangeably as long as their firearm is rated for the caliber.

Some Quick Specifications and Variables to Consider

A true comparison requires an understanding of the specifications. Here we present a detailed scrutiny of the caliber, bullet weight, and velocity among other aspects.

• Caliber: Both ammunition types come under the .22 caliber category, with distinct differences lying in their power and performance. Due to their .22” bores, firearms in either caliber can utilize the same cleaning tools in addition to accessories such as muzzle devices and suppressors in some cases.
• Bullet Weight: The .22 LR generally features a lighter bullet, ranging from 30 to 40 grains, whereas the .22 WMR offers a heavier bullet weight, mostly lying in the 30 to 50 grains range.
• Velocity: When it comes to velocity, the .22 WMR takes the lead with faster muzzle velocities compared to the .22 Long Rifle, ensuring a higher impact on the target. .22 LR velocities average out at around 1,100 – 1,400 FPS while average .22 WMR velocities lie between 1,500 – 1,875 FPS depending on host firearm and barrel length. Of course, certain loadings in either round can achieve velocities at higher and lower speeds than the aforementioned ranges.
• Precision and Accuracy: While both ammunition types promise a commendable level of accuracy, the .22 WMR stands a notch higher, especially for long-range shots, attributing to its higher velocities and energies. There is simply more power behind .22 WMR loadings than there is behind .22 LR loadings. Additionally, the .22 WMR offerings generally boast flatter trajectories than .22 LR loadings do.
• Cost-Efficiency: If budget-friendliness is a priority, the .22 LR emerges as the clear winner, offering affordability without compromising significantly on performance. This is to say that shooters can acquire .22 LR ammunition at cheaper prices, often in bulk form, than they can acquire .22 WMR ammo.
• Ammo Availability: One will have an easier time finding .22 LR ammunition than they will finding .22 WMR ammo. The .22 LR round simply sees a wider range of support from ammo producers and tends to be present at most places where ammunition is sold. This is not to say that .22 WMR ammo is impossible to find, it is just not nearly as common or accessible as .22 LR ammo.
• Availability of Firearms: Currently, there are more options in the way of .22 LR firearms than there are for .22 WMR. This is mainly due to the fact that the cartridge has been around longer and has developed a greater foothold in the market than the .22 WMR. Shooters will find more pistols, rifles, and revolvers chambered in .22 LR than they will in .22 WMR.
• Suppression: The .22 LR cartridge is more optimal for suppressed shooting than the .22 WMR is. This is due to the fact that most .22 LR standard velocity loadings are operating at subsonic velocities, especially when used in pistol barrels. These lower velocities pair well with suppressors and help produce truly “Hollywood quiet” noise levels.
