Sierra 1615 GameKing 25 Cal 90gr HPBT Bullets 100/Box

The Sierra 1615 GameKing delivers exceptional accuracy and controlled expansion for 25 caliber hunting applications. This 90-grain hollow point boat tail bullet combines Sierra's proven GameKing design with precision manufacturing to ensure consistent performance on medium game. The boat tail configuration reduces drag and maintains velocity downrange while the hollow point design provides reliable expansion upon impact.

What Makes This Different

Sierra's GameKing bullets feature a unique jacket design that controls expansion while maintaining weight retention. The boat tail base reduces air resistance by approximately 6-8% compared to flat base bullets, resulting in flatter trajectory and less wind drift. The hollow point cavity is precisely formed to initiate expansion at velocities as low as 1,800 fps, making it effective across a wide range of hunting distances.

Key Features

• 90-grain hollow point boat tail design for controlled expansion
• Boat tail base reduces drag and improves ballistic coefficient
• Tapered jacket construction ensures reliable weight retention
• Hollow point cavity optimized for expansion at hunting velocities
• Consistent bullet-to-bullet weight variance under 0.3 grains
• Compatible with standard 25 caliber rifles (.257 Roberts, .25-06, .257 Weatherby)
• Manufactured to Sierra's precision tolerances for match-grade accuracy

Field testing demonstrates this bullet's effectiveness on deer-sized game at ranges from 100 to 400 yards. The hollow point design creates a wound channel that ensures quick, humane kills while the boat tail configuration maintains accuracy at extended distances. The bullet performs consistently in various weather conditions and maintains stability through crosswinds better than conventional flat base designs.
