.224 Valkyrie

The .224 Valkyrie (5.6×41 mm) 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). The case is based on that of the 6.8mm Remington SPC, which in turn was based on the .30 Remington.
