The .224 Valkyrie is a centerfire rifle cartridge developed by Federal Premium Ammunition, an American ammunition manufacturer. It was introduced in 2017 and designed specifically for long-range shooting using the AR-15 platform, with the goal of providing superior ballistics and performance compared to the .223 Remington/5.56 NATO cartridges.
The .224 Valkyrie is based on the 6.8 SPC case, necked down to accept a .22 caliber (5.6mm) bullet. The cartridge is designed to handle heavier, high-ballistic-coefficient bullets, providing better long-range performance, reduced wind drift, and flatter trajectories than other .22 caliber cartridges in the AR-15 platform. Typical bullet weights for the .224 Valkyrie range from 60 to 90 grains, with muzzle velocities between 2,700 and 3,300 feet per second, depending on the bullet weight and load.
One of the main advantages of the .224 Valkyrie is its ability to remain supersonic at distances beyond 1,000 yards, which is critical for maintaining accuracy and energy at long ranges. The .224 Valkyrie has gained popularity among long-range competitive shooters and hunters targeting medium-sized game and varmints at extended distances, thanks to its impressive ballistics and compatibility with the widely popular AR-15 platform.
