The 224 Valkyrie is based on a 30 Rem./6.8 SPC case necked down to .224 caliber. This gives it similar geometry to the 22 Nosler — although the Valkyrie’s ingenious blend of case capacity and ample ogive space, coupled with a highly efficient, heavy-for-caliber .224 projectile, produces downrange exploits the 22 Nosler can’t touch.”
“It offers up to 127.88 inches less drop and 68.76 inches less wind drift at 1,000 yards than the 223 Rem and other short-action calibers like the 22 Nosler and 6.5 Grendel. Plus, its ballistics are comparable to much larger, harder-kicking calibers like the 6.5 Creedmoor — with as little as half the felt recoil.”
Another factor is speed. Federal tested its 224 Valkyrie 90-grain Gold Medal Sierra MatchKing and had it leaving the muzzle at 2,700 feet per second. Federal reported that speed maintained at a pace of 1,950 fps at 500 yards and 1,268 fps when crossing the 1,000-yard line.
