Sierra GameKing 6.5mm 120gr HPBT Bullets - 500 Count Box 4320C

The Sierra GameKing 4320C delivers exceptional accuracy and controlled expansion for 6.5mm cartridges, engineered with Sierra's proven hollow point boat tail design. These 120-grain bullets feature precise manufacturing tolerances that produce consistent ballistic performance across hunting and precision shooting applications.

What Makes This Different

Sierra's GameKing line utilizes a specialized jacket design that maintains structural integrity during flight while ensuring reliable expansion on impact. The hollow point boat tail configuration reduces drag coefficient by approximately 15% compared to flat base designs, extending effective range and improving wind resistance. Each bullet undergoes multiple quality control inspections to maintain weight variance within ±0.3 grains.

Key Features

• 120-grain hollow point boat tail design optimized for 6.5mm cartridges
• Sectional density of 0.246 provides excellent penetration characteristics
• Ballistic coefficient of 0.400 (G1) maintains velocity at extended ranges
• Tapered jacket construction ensures controlled expansion from 1,800-3,200 fps
• Precision swaged lead core eliminates air pockets and weight inconsistencies
• 500-count bulk packaging reduces cost per round for high-volume shooters
• Compatible with all standard 6.5mm cartridges including Creedmoor, Grendel, and Swedish Mauser

Field testing demonstrates consistent 1-2 MOA accuracy in quality rifle systems when properly loaded. The boat tail design maintains supersonic flight beyond 1,000 yards in most 6.5mm cartridges, making these bullets suitable for long-range hunting and competitive shooting disciplines. The controlled expansion characteristics perform effectively on medium game from whitetail deer to elk-sized animals.
