8mm 150Gr Sptz/100 Description 8mm Spitzer SP - Soft Point Diameter: .323 Weight: 150gr Ballistic Coefficient: 0.369 Box Count: 100 Vernon Speer was a very smart man. He developed a process to improve rifle bullet integrity and called it Hot-Cor. Hot-Cor means tat the lead core is poured into the jacket while molten. This virtually eliminates the core slippage so common to bullets assembled with a cold lead slug. This process makes it a great bullet with the penetration and expansion needed for larger game. Note: These are component bullets not loaded ammunition.
