Speer Grand Slam rifle bullets in 7mm, 145 grains (Speer part no. 1632), have been a favorite among hunters who demand outstanding performance since the line was introduced in the 1970s, and the design has changed little because it works. A tapered, precision-drawn jacket with internal flutes is fused to the core through Speer’s Hot-Cor process, and that jacket-and-core fusion delivers symmetrical, consistent expansion on impact instead of the erratic performance a poorly bonded bullet can show. For 7mm hunters who need a tough, reliable bullet with real weight retention on deer-class and larger game, the Grand Slam remains a proven choice decades after its introduction.
