The Weatherby 224 WBY Mag 55gr Spire Point load is a box of 20 rounds of 224 Weatherby Magnum hunting ammunition built on premium brass (Weatherby part no. H22455SP). Weatherby calls the 224 Weatherby Magnum one of the fastest .22 caliber cartridges ever released in a factory rifle, a round Roy Weatherby built from the ground up with no true parent case. The Hornady Spire Point has an exposed lead tip for controlled expansion on a secant ogive, and a raised ring inside the jacket locks the jacket to the one-piece core during expansion. Each box holds 20 rounds, so one purchase covers a range session to confirm zero and a few shots in the field. Weatherby says factory loads can exceed 4,125 feet per second and positions the cartridge for coyotes, prairie dogs and other small game.
