Speer 1415 Grand Slam 25Cal 120gr Soft Point projectiles are built for maximum integrity on large-bodied game. The construction features a ternary lead alloy core molten-bonded to a precision-drawn jacket with internal fluting for symmetrical expansion. A rear lock ring prevents core-jacket separation, while the thick jacket shank ensures deep penetration through heavy bone. This 120-grain design is the heavy-hitter of the .25 caliber world, offering the knockdown power and weight retention needed for ethical harvests of elk and large deer. Defensive Application Engineered for deep penetration on large animals, these bullets pose a significant over-penetration risk in residential environments and are not recommended for home defense.
