The .223 Remington is a widely used, intermediate, smokeless rifle cartridge developed around 1964, closely associated with the AR-15 platform and varmint hunting due to its high velocity, flat trajectory, and low recoil. It is commonly used for varmint hunting, target shooting, and, with proper bullet selection, medium-sized game, featuring a typical muzzle velocity of 3,000-3,300+ fps.
Key Details and Characteristics:
- Performance & Range: With effective performance for varmints often exceeding 300-400 yards, it is prized for high terminal energy transfer.
- Common Uses:
Varmint hunting, predator control (coyotes, foxes), target shooting, and recreational shooting
. - Rifles: Chambered in bolt-action rifles, AR-15s, and various other semi-automatic rifles.
- Ammunition & Bullet Types: Available in numerous grain weights (often 40-77 grains) and types, including Full Metal Jacket (FMJ) for target practice, as well as hollow point and soft point for hunting.
- 223 Remington vs. 5.56 NATO: While outwardly similar, they are not identical. 5.56 NATO often operates at higher pressures, and using 5.56 in a rifle chambered specifically for .223 Remington may cause safety issues, although the reverse is generally acceptable.
- Effective Range: While often used for varmints at 300+ yards, it is often considered a 200-300 yard cartridge for larger game like deer, depending on bullet construction and velocity.
