The Speer Grand Slam 25 caliber 120-grain soft point bullets deliver consistent expansion and deep penetration for medium game hunting. These premium hunting bullets feature Speer's proven dual-core construction that maintains weight retention while providing reliable terminal performance across various hunting scenarios.
What Makes This Different
The Grand Slam's unique dual-core design separates it from conventional soft point bullets through its bonded front core and solid rear core construction. This engineering approach ensures the front section expands predictably for maximum energy transfer while the rear core drives deep for complete penetration. The result is superior weight retention compared to standard cup-and-core bullets, typically maintaining 65-75% of original bullet weight.Key Features
