The debate between the .22 WMR (Winchester Magnum Rimfire) and the 5.7x28mm cartridges has been a topic of interest for firearms enthusiasts and hunters alike. Both cartridges offer unique advantages and have their own set of loyal followers. In this article, we will delve into the world of these two powerful rounds, exploring their origins, performance, and suitability for various shooting applications.
The .22 WMR: A Rimfire Legend
The .22 WMR, often referred to as the .22 Magnum, is a rimfire cartridge that has left an indelible mark on the shooting industry. Introduced by Winchester in 1959, it was designed to provide shooters with a more powerful option compared to the standard .22 Long Rifle (LR) round. With its higher velocity and energy, the .22 WMR quickly gained popularity among hunters and target shooters.
Key Characteristics of the .22 WMR:
- Caliber: 0.224 inches.
- Bullet Weight: Typically ranges from 30 to 60 grains.
- Muzzle Velocity: Approximately 1,700 to 2,400 fps (feet per second), depending on the load.
- Energy: Offers significant energy at close ranges, making it suitable for small game hunting.
- Recoil: Minimal recoil due to its lightweight and low-pressure design.
The .22 WMR is known for its accuracy and versatility. It is commonly used for varmint hunting, pest control, and small game hunting, such as squirrels and rabbits. Its low recoil makes it an excellent choice for shooters who prefer a comfortable shooting experience.
The 5.7x28mm: A Modern Firepower
On the other hand, the 5.7x28mm cartridge is a relatively newer addition to the firearms world. Developed by FN Herstal in the early 1990s, it was initially designed for military and law enforcement applications. The 5.7x28mm cartridge offers a unique combination of high velocity and low recoil, making it a popular choice for both defensive and sporting purposes.
Key Characteristics of the 5.7x28mm:
- Caliber: 5.7x28mm (0.224 inches)
- Bullet Weight: Typically ranges from 25 to 55 grains.
- Muzzle Velocity: Impressive speeds of around 2,500 to 3,000 fps.
- Energy: Delivers substantial energy, ideal for self-defense and target shooting.
- Recoil: Minimal recoil, making it suitable for rapid-fire situations.
The 5.7x28mm cartridge gained recognition for its use in the FN P90 and Five-seveN pistols. Its high velocity and flat trajectory make it an excellent choice for personal defense, as it can effectively penetrate barriers and provide accurate long-range shots. Additionally, its low recoil allows for faster follow-up shots, enhancing its effectiveness in critical situations.
Performance Comparison: Which is the Ultimate Choice?
When comparing the .22 WMR and the 5.7x28mm, it's essential to consider their intended purposes and performance characteristics.
Ballistics and Trajectory:
The 5.7x28mm cartridge boasts higher muzzle velocities and a flatter trajectory, making it an excellent choice for long-range shooting. Its supersonic speed and low drag coefficient allow it to maintain its velocity over extended distances. On the other hand, the .22 WMR, while powerful, has a shorter effective range due to its lower velocity.
| Cartridge | Muzzle Velocity (fps) | Effective Range (yards) |
|---|---|---|
| 5.7x28mm | 2,500 - 3,000 | 200+ yards |
| .22 WMR | 1,700 - 2,400 | 100-150 yards |
Recoil and Shootability:
Both cartridges offer minimal recoil, but the .22 WMR takes the lead in terms of comfort. Its lightweight and low-pressure design result in a smooth shooting experience, making it ideal for shooters who prioritize recoil management. The 5.7x28mm, while also having low recoil, may be slightly snappier due to its higher velocity.
Ammunition Availability and Cost:
Ammunition availability and cost are crucial factors to consider. The .22 WMR, being a well-established cartridge, is widely available and relatively affordable. On the contrary, the 5.7x28mm, being a more specialized round, may have limited availability and higher costs.
Application-Specific Considerations:
- Hunting: The .22 WMR is an excellent choice for small game hunting due to its accuracy and suitable energy levels. It is perfect for taking down squirrels, rabbits, and other small game within its effective range.
- Self-Defense: The 5.7x28mm shines in self-defense scenarios. Its high velocity and penetration capabilities make it an ideal choice for personal protection, ensuring effective barrier penetration and accurate long-range shots.
- Target Shooting: Both cartridges excel in target shooting. The .22 WMR offers precision and affordability, making it a popular choice for plinking and target practice. The 5.7x28mm, with its flat trajectory, provides an added advantage for long-range precision shooting.
Choosing the Right Cartridge for Your Needs
The decision between the .22 WMR and the 5.7x28mm ultimately depends on your specific shooting requirements. If you prioritize accuracy, comfort, and affordability for small game hunting or target shooting, the .22 WMR is an excellent option. However, if you seek a cartridge with exceptional long-range performance, high velocity, and penetration capabilities for self-defense or competitive shooting, the 5.7x28mm is the way to go.
Wrapping Up
