The Hornady Bullets 7mm .284 - 139gr JSP 100ct is a precision rifle cartridge component engineered for serious hunters, precision rifle competitors, and law enforcement marksmen who demand consistent, predictable bullet performance downrange. Hornady's JSP (Jacketed Soft Point) design has established itself as a proven platform across thousands of hunting seasons and tactical applications, offering reliable expansion paired with deep penetration characteristics essential for ethical game harvesting and duty-grade accuracy requirements.
These 139-grain projectiles feature a .284-inch diameter optimized for 7mm calibers (7mm Remington Magnum, 7mm-08 Remington, and 280 Remington platforms), with a ballistic coefficient of .392 and sectional density of .246 that translate to excellent velocity retention and stable flight characteristics at extended ranges. The JSP construction incorporates strategically placed inner grooves that weaken the upper jacket section, promoting controlled expansion upon impact while the heavy-duty jacket construction maintains structural integrity through intermediate barriers. This controlled-expansion design minimizes over-expansion while preventing jacket/core separation—critical reliability factors for duty ammunition and big-game applications where shot placement demands consistency across variable medium conditions.
The 100-count box format (25 boxes per case) serves reloaders preparing ammunition for 7mm rifle systems, offering convenient tracking and inventory management for high-volume shooters and ammunition manufacturers. Shooters using 7mm Remington Magnum, 7mm-08, or .280 Remington platforms will find these bullets deliver the ballistic stability and terminal performance required for 300+ yard precision work, whether for competitive long-range competitions, hunting applications, or training regimens. Verify your specific rifle's barrel twist rate and seating depth recommendations before reloading to optimize accuracy and safety.
