## Understanding the .22 WMR and .22 Magnum
### .22 WMR: A Deep Dive
The .22 Winchester Magnum Rimfire (WMR), often referred to simply as the .22 Magnum, is a rimfire cartridge developed by Winchester in 1959. It was designed to offer a significant power upgrade over the ubiquitous .22 Long Rifle (.22 LR) while still maintaining the advantages of a rimfire ignition system, namely relative affordability and simplicity. The .22 WMR quickly gained popularity for varmint hunting, small game hunting, and target shooting, filling a niche between the .22 LR and centerfire cartridges like the .22 Hornet.
At its core, the .22 WMR is a longer and wider cartridge than the .22 LR, allowing it to hold a larger powder charge and accommodate heavier bullets. This translates to significantly higher velocities and energy levels. While the basic principle is simple, the .22 WMR’s design incorporates several nuances that contribute to its performance. The case is typically made of brass, and the bullet is crimped tightly into the case mouth to ensure consistent ignition and prevent bullet setback during feeding.
The importance of the .22 WMR lies in its versatility. It provides a flatter trajectory and greater range than the .22 LR, making it suitable for longer-range shots on small game and varmints. Its higher energy also makes it more effective for hunting larger animals like rabbits, squirrels, and even coyotes at reasonable distances. The .22 WMR remains highly relevant today as a capable and affordable option for shooters who need more power than the .22 LR but don’t want to step up to a centerfire cartridge.
### .22 Magnum: Clarifying the Terminology
Here’s where things get a little tricky. The term “.22 Magnum” is almost universally used interchangeably with “.22 WMR.” They refer to the *same* cartridge. While technically, “.22 Magnum” could theoretically refer to other hypothetical .22 caliber magnum cartridges, in practical usage and common parlance, it *always* means the .22 Winchester Magnum Rimfire.
Consider this analogy: Think of Kleenex. It’s a brand name for facial tissue, but people often use “Kleenex” to refer to any facial tissue, regardless of the manufacturer. Similarly, “.22 WMR” is the specific cartridge designation, while “.22 Magnum” is the more common, generalized term that everyone understands to mean the same thing.
To avoid confusion, this article will primarily use “.22 WMR” to maintain technical accuracy, but understand that “.22 Magnum” is simply the more colloquial term for the same thing.
## Ballistic Performance: .22 WMR vs .22 Mag
Let’s get into the numbers. The ballistic performance is where the .22 WMR truly shines compared to the .22 LR. Several factors influence ballistic performance, including bullet weight, bullet type, and barrel length. The following data provides a general comparison based on common ammunition offerings.
* **Velocity:** The .22 WMR typically achieves velocities of 1800-2000 feet per second (fps) with a 40-grain bullet, depending on the barrel length. This is significantly faster than the .22 LR, which typically achieves velocities of 1200-1400 fps with the same bullet weight.
* **Energy:** The higher velocity of the .22 WMR translates to significantly higher energy levels. A 40-grain .22 WMR bullet typically delivers around 300-350 foot-pounds of energy at the muzzle, compared to around 130-150 foot-pounds for the .22 LR.
* **Trajectory:** The flatter trajectory of the .22 WMR makes it easier to hit targets at longer ranges. The .22 WMR typically drops less than the .22 LR at distances beyond 100 yards.
* **Effective Range:** The .22 WMR has a longer effective range than the .22 LR. While the .22 LR is typically considered effective out to 75-100 yards, the .22 WMR can be effective out to 125-150 yards or even further, depending on the shooter’s skill and the specific ammunition.
These numbers highlight the significant ballistic advantage of the .22 WMR over the .22 LR. The higher velocity, energy, and flatter trajectory make it a more capable cartridge for hunting and target shooting at longer ranges.
