Sierra 1630 GameKing 25 Cal 117gr Spitzer Boat Tail Bullets 100/Box

The Sierra 1630 GameKing delivers exceptional accuracy and terminal performance for 25 caliber hunting applications. This 117-grain spitzer boat tail bullet combines Sierra's proven GameKing design with aerodynamic efficiency for extended range capabilities. Hunters rely on these bullets for consistent expansion and deep penetration on medium game.

What Makes This Different

The GameKing's boat tail design reduces drag coefficient by approximately 15% compared to flat-base bullets, extending effective range and maintaining velocity downrange. Sierra's proprietary jacket construction ensures controlled expansion while the pointed spitzer profile delivers superior ballistic coefficient. This combination produces flatter trajectories and increased energy retention at hunting distances.

Key Features

• 117-grain weight optimized for 25 caliber cartridges including .257 Roberts and .25-06 Remington
• Spitzer boat tail design with BC of approximately 0.391 for enhanced long-range performance
• Tapered jacket construction promotes controlled expansion on medium game
• Lead core precisely matched to jacket for consistent weight distribution
• Boat tail base reduces drag and wind drift at extended ranges
• 100-count bulk packaging for serious hunters and reloaders
• Quality control standards ensure consistent diameter and weight tolerances

Field testing demonstrates reliable expansion at velocities between 1,800-3,000 fps, making these bullets suitable for various 25 caliber cartridges. The GameKing performs effectively on deer-sized game at ranges extending beyond 300 yards when launched from appropriate cartridges. Weather conditions have minimal impact on accuracy due to the aerodynamic boat tail configuration.
