Speer Grand Slam Bullets were developed to give hunters a tough, dependable bullet that would provide better integrity and retained weight retention over similar bullets. Since first being introduced in the 1970's the Grand Slam bullet has gained a reputation for providing hunters superior performance, exceptional accuracy and real knockdown power. The bullet has a tapered, precision-drawn jacket with internal flutes which are fused to the soft lead through the Hot-Cor process. This core fusion and jacket design help the bullet to deliver reliable, symmetrical, consistent expansion upon impact. The long nose profile helps to provide a flatter shooting bullet that will take down game at the edge of your rifles capability. This is not loaded ammunition.
