.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. .224 Valkyrie uses the same bullet diameter as 5.56×45mm NATO and a necked down larger case from the 6.8 SPC allowing for heavier bullets and higher muzzle velocity.
