Sierra 1390 GameKing 22Cal 55gr HPBT Bullets 100/Box

The Sierra 1390 GameKing delivers exceptional accuracy and terminal performance for varmint hunting and target shooting applications. These 55-grain hollow point boat tail bullets feature Sierra's proven GameKing design, engineered to expand reliably on medium game while maintaining the precision demanded by competitive shooters.

What Makes This Different

Sierra's GameKing construction combines a tapered jacket with a hollow point cavity optimized for controlled expansion at .22 caliber velocities. The boat tail base reduces drag coefficient by approximately 15% compared to flat base designs, extending effective range and improving wind resistance. Manufacturing tolerances held to ±0.3 grains ensure consistent ballistic performance across the entire lot.

Key Features

• 55-grain hollow point boat tail configuration for optimal expansion and accuracy
• Tapered copper jacket thickness provides controlled expansion on varmints
• Boat tail base design reduces drag and improves long-range trajectory
• Match-grade manufacturing with weight tolerance of ±0.3 grains
• Compatible with .223 Remington, .22-250, and similar .224" bore cartridges
• Sectional density of 0.157 for adequate penetration on medium game
• 100-count bulk packaging for high-volume shooting applications

Field testing demonstrates consistent sub-MOA accuracy in quality bolt-action rifles when paired with appropriate powder charges. The hollow point design initiates rapid expansion on prairie dogs, ground squirrels, and similar varmints while the boat tail configuration maintains velocity downrange. These bullets perform effectively in both hunting scenarios and competitive shooting disciplines requiring precision at extended ranges.
