As a seasoned outdoor writer and adventurer, I’ve spent years exploring the capabilities of various firearms. One cartridge that consistently sparks debate and delivers impressive performance is the .22 WMR, also known as the .22 Winchester Magnum Rimfire. This isn’t your grandfather’s .22 Long Rifle. The .22 WMR offers a significant step up in power and range, making it a versatile option for small game hunting, pest control, and even, in some cases, larger varmint or deer hunting. In this comprehensive guide, we’ll dive deep into the world of the .22 Magnum, covering its ballistics, hunting applications, ammo choices, and how it stacks up against other popular cartridges.
What is the .22 WMR? A History and Overview
Introduced in 1959 by Winchester, the .22 WMR was designed to address the limitations of the .22 Long Rifle. The .22 LR, while incredibly popular, lacked the velocity and energy needed for consistent performance on larger small game or at extended ranges. The .22 WMR achieves this by utilizing a longer case and a heavier bullet, resulting in significantly higher velocities – typically around 2,000 feet per second (fps) with a 40-grain bullet. This increased velocity translates to a flatter trajectory and more downrange energy. You can find more historical information on Winchester’s website here.
.22 WMR vs. .22 LR: Key Differences
- Velocity: .22 WMR averages 2,000 fps, while .22 LR typically ranges from 1,000-1,300 fps.
- Energy: .22 WMR delivers significantly more energy at all ranges.
- Range: .22 WMR is effective at longer distances, generally out to 150-200 yards.
- Cost: .22 WMR ammunition is generally more expensive than .22 LR.
.22 WMR Ballistics: Understanding Trajectory and Performance
Understanding the ballistics of the .22 WMR is crucial for accurate shooting and ethical hunting. Factors like bullet weight, muzzle velocity, and atmospheric conditions all play a role. Here’s a look at typical ballistics for common .22 WMR loads. Remember to always consult a specific .22 magnum ballistics chart for the ammunition you are using, as variations exist.
CCI 22 Magnum Ballistics Chart (Example)
While specific data varies, here’s an example based on CCI’s 40-grain JSP load (data sourced from CCI’s website here):
| Distance (Yards) | Drop (Inches) | Velocity (fps) |
|---|---|---|
| 50 | 0.4 | 1,980 |
| 100 | 2.1 | 1,840 |
| 150 | 4.3 | 1,690 |
| 200 | 6.9 | 1,530 |
A .22 magnum trajectory chart is essential for making accurate shots at varying distances. Many online ballistics calculators (like those offered by Hornady here) can generate customized charts based on your specific ammunition and rifle.
50 Grain 22 WMR Ballistics
Heavier 50-grain bullets, like the 50 grain 22 mag offered by Federal, generally offer better energy retention and wind resistance, making them ideal for longer-range shooting and larger varmints. However, they also experience more drop than lighter bullets.
Hunting with the .22 WMR: What Can It Take?
The .22 WMR is a highly effective cartridge for a wide range of small game and varmint hunting. Its flat trajectory and increased energy make it a significant improvement over the .22 LR for these applications.
Small Game Hunting
The .22 WMR excels at taking down:
- Squirrels
- Rabbits
- Foxes
- Groundhogs
- Prairie Dogs
Can a .22 Magnum Kill a Deer?
This is a frequently asked question. While it can be done, it’s a controversial topic. The .22 WMR is generally considered marginal for deer hunting, and ethical considerations are paramount. Many states prohibit its use for deer. If legal in your area, it requires a very accurate shot placement – a double-lung or heart shot – and is best suited for smaller deer at close ranges (under 100 yards). The National Shooting Sports Foundation (NSSF) provides information on hunting regulations by state here. I personally recommend using a more powerful cartridge for deer hunting whenever possible.
Best 22 Mag Ammo for Coyotes
For coyotes, heavier bullets like the federal 50 grain 22 magnum ammo or similar loads from CCI and Winchester are preferred. These offer better penetration and energy transfer for a clean kill. Shot placement is critical, aiming for the vitals.
.22 WMR vs. Other Cartridges: How Does It Stack Up?
Let’s compare the .22 WMR to some other popular cartridges.
.22 WMR vs. 9mm
The .22 magnum vs 9mm debate often arises. The 9mm is a significantly more powerful cartridge designed for self-defense and larger game. It delivers far more energy and has a much flatter trajectory at longer ranges. The .22 WMR is not a substitute for a 9mm in a defensive situation.
.22 WMR vs. .22 Hornet
The .22 hornet vs 22 mag comparison is more nuanced. The .22 Hornet generally offers superior ballistics, with higher velocities and energy. However, .22 Hornet ammunition is often more expensive and harder to find. The .22 WMR provides a good balance of performance and affordability.
.22 WMR vs. .22 WRF
The .22 wrf vs 22 mag is another common comparison. The .22 WRF (Winchester Rimfire) is a slightly more powerful cartridge than the .22 LR but less powerful than the .22 WMR. The .22 WMR generally offers a flatter trajectory and more energy.
Choosing the Right .22 WMR Rifle and Ammunition
Numerous rifles are chambered in .22 WMR, from bolt-action to semi-automatic. A remington 22 magnum bolt action rifle is a popular choice for accuracy and reliability. Consider your intended use when selecting a rifle. For varmint hunting, a bolt-action with a good scope is ideal. For plinking and casual shooting, a semi-automatic may be more fun.
Most Accurate 22 Magnum Ammo
Accuracy varies between rifles, but generally, CCI and Federal ammunition are known for their consistent performance. Experiment with different brands and bullet weights to find what shoots best in your firearm.
Safety Considerations and Responsible Gun Ownership
Always practice safe gun handling procedures. Treat every firearm as if it is loaded. Be aware of your target and what is beyond it. Follow all local and state laws regarding firearm ownership and use. The National Rifle Association (NRA) offers comprehensive safety courses here. And remember the principles of Leave No Trace here when enjoying the outdoors.
The .22 WMR is a versatile and capable cartridge that deserves consideration for a variety of outdoor applications. By understanding its ballistics, hunting potential, and limitations, you can make informed decisions and enjoy a safe and rewarding shooting experience.
