Ride the Federal 224 Valkyrie Ron Spomer Outdoors
What Makes the Federal 224 Valkyrie Work. The magic behind the Valkyrie is not a short/fat case, not world record muzzle velocity, world record accuracy or world record terminal energy. The magic is long, extremely high bullets helped along by 17″ rifling twist rates and slightly more powder than the old 223 Remington can provide.
