- Caliber: .224 inches (5.7 mm)
- Case Length: 1.087 inches (27.6 mm)
- Bullet Weights: Typically range from 30 to 60 grains
- Muzzle Velocity: Varies depending on bullet weight and load, but can reach speeds of up to 2,100 feet per second (640 m/s)
- Muzzle Energy: Approximately 400–700 foot-pounds force (540–950 joules)
The .22 WMR's performance is influenced by factors such as bullet weight, velocity, and construction. It offers excellent accuracy and is capable of taking small game and varmints effectively within its intended range.
Ammunition Options
The .22 WMR cartridge is available in a wide range of ammunition options, catering to different shooting preferences and purposes. Here are some common types of .22 WMR ammunition:
High-Velocity Loads
These loads are designed for maximum velocity and are often used for varmint hunting and target shooting. They typically feature lightweight bullets, such as 30-grain or 40-grain, and can achieve impressive speeds.
Standard Velocity Loads
Standard velocity loads offer a balanced approach, providing good accuracy and performance for various applications. They are suitable for hunting, pest control, and recreational shooting.
Subsonic Loads
Subsonic loads are specifically designed to operate at speeds below the speed of sound, resulting in suppressed firing and reduced report. These loads are commonly used in conjunction with suppressors and are popular among shooters who prioritize stealth and quietness.
Hollow Point and Soft Point Bullets
Hollow point and soft point bullets are ideal for hunting and self-defense purposes. They offer controlled expansion, maximizing energy transfer upon impact. These bullets are designed to deliver maximum stopping power while minimizing over-penetration.
Lead-Free Options
For those concerned about lead exposure or environmental impact, lead-free .22 WMR ammunition is available. These rounds typically use copper-plated bullets or non-toxic materials, ensuring a more environmentally friendly shooting experience.
