The .224 Valkyrie (5.6×41 mm)[5] cartridge is a .22 caliber (5.6 mm) rimless bottlenecked intermediate rifle cartridge, developed by Federal Premium Ammunition to rival the performance of the .22 Nosler, while still being compatible with modern sporting rifles (MSRs).

[4] The case is based on that of the 6.8mm Remington SPC, which in turn was based on the .30 Remington.
