Sierra GameKing 117 Grain Bullet in .25 Caliber
The Sierra GameKing 117 grain bullet represents a pinnacle in precision projectile engineering for hunters specializing in medium-sized game. Chambered for the .25 caliber (0.257 inches), this bullet features a meticulously crafted Spitzer Boat Tail profile, which significantly enhances its ballistic coefficient. This aerodynamic configuration reduces drag and wind drift, resulting in flatter trajectories and superior energy retention over extended ranges, making it an ideal choice for precision shooting and metallic reloading enthusiasts seeking optimized performance.
Key Technical Features
- Aerodynamic Profile: The Spitzer nose cone combined with the Boat Tail base design minimizes air resistance, enabling sustained velocities and improved downrange stability, essential for long-range hunting scenarios.
- Premium Construction: Manufactured using Sierras exclusive four-step jacket forming process, this bullet exhibits exceptional concentricity and uniformity. The semi-metallic jacket ensures consistent barrel engagement, reducing fouling and enhancing accuracy shot after shot.
- Terminal Ballistics: Engineered for reliable expansion and deep penetration, the GameKing 117 grain bullet delivers controlled hydrostatic shock and tissue damage, optimizing lethality on medium game targets at distances ranging from 200 to 500 yards.
Technical Specifications
| Caliber | .25 (0.257 inches) |
|---|---|
| Bullet Weight | 117 grains |
| Sectional Density | 0.253 |
| Ballistic Coefficient (G1) | 0.410 at velocities exceeding 2,500 fps |
| Recommended Rifling Twist | 1:10 or faster |
Reloading and Usage Guidelines
To maximize the ballistic potential and terminal effectiveness of the Sierra GameKing 117 grain bullet, consider the following recommendations:
- Powder Selection and Load Development: Utilize powders and charge weights that achieve muzzle velocities above 2,500 feet per second to fully exploit the bullets aerodynamic efficiency and ballistic coefficient.
- Barrel Specifications: Employ barrels with rifling twist rates of 1:10 or faster to ensure gyroscopic stability and maintain bullet integrity throughout the trajectory.
- Application Suitability: This bullet excels in medium game hunting applications, offering a balanced combination of expansion reliability and penetration depth, crucial for ethical and effective harvests.
Additional Considerations
While the Sierra GameKing bullets are globally recognized for their unmatched accuracy and dependable terminal performance, hunters and reloaders should always evaluate game species, environmental conditions, and local hunting regulations when selecting ammunition. Adhering to ethical hunting practices and ensuring compliance with legal standards is paramount for responsible firearm use.
