Speer Grand Slam Soft Point bullets are engineered to tackle the world's toughest and largest game. These projectiles utilize a unique dual-core design: a soft lead nose bonded via the Hot-Cor process for immediate expansion, and a much harder rear core that is mechanically locked into the jacket to ensure the bullet remains a single, high-mass unit. This structural integrity allows the bullet to punch through heavy bone and thick hide without fragmenting, while the internal fluting ensures a classic, wide mushroom. It is an elite choice for hunters who require both match-grade accuracy at distance and unstoppable terminal performance on impact for big-game species. Defensive Application These heavy, bonded big-game bullets are designed for deep-tissue penetration. They present an extreme over-penetration risk in residential settings and are not recommended for home defense.
