Sierra GameKing 338 Cal 250gr Spitzer Boat Tail Bullets 50/Box

The Sierra GameKing 338 caliber 250-grain bullets deliver exceptional accuracy and controlled expansion for big game hunting at extended ranges. These precision-engineered projectiles combine proven boat tail design with Sierra's renowned quality control standards to ensure consistent performance shot after shot.

What Makes This Different

Sierra's GameKing bullets feature a unique jacket design that maintains structural integrity while providing reliable expansion on impact. The spitzer boat tail profile reduces drag by approximately 15% compared to flat-base designs, extending effective range and improving wind resistance. Each bullet undergoes multiple quality inspections during manufacturing to maintain weight consistency within ±0.3 grains.

Key Features

• 250-grain weight optimized for .338 Winchester Magnum and similar cartridges
• Spitzer boat tail design for superior ballistic coefficient and downrange energy retention
• Tapered jacket construction ensures controlled expansion at velocities from 1,800-3,200 fps
• Lead core bonding process minimizes weight loss during penetration
• Precision-drawn gilding metal jacket for consistent concentricity
• 50-count box packaging with individual bullet inspection
• Compatible with standard reloading dies and powder charges

Field testing demonstrates these bullets maintain over 85% weight retention while creating wound channels 2-3 times bullet diameter in ballistic gelatin. The boat tail configuration reduces wind drift by 20-25% at 400 yards compared to flat-base alternatives. Hunters report reliable performance on elk, moose, and large African game species across temperature ranges from -20°F to 120°F.
