Speer 1624 Boat-Tail 7mm 130gr JSPBT bullets are engineered for the hunter seeking to maximize effective range and trajectory. The boat-tail design significantly reduces base drag, providing a flatter flight path and less wind deflection than flat-base alternatives. With a 130-grain weight, these bullets are optimized for high-velocity 7mm cartridges, offering rapid expansion and massive energy transfer on impact. They are a premier choice for open-country hunting of white-tailed deer, mule deer, and antelope. Defensive Application Optimized for hunting at distance, these bullets provide rapid expansion and deep penetration, but pose a significant over-penetration risk for home defense applications.
