Sierra 1365 GameKing 22 Cal 55gr Spitzer Boat Tail Bullets 100/Box

The Sierra 1365 GameKing delivers consistent accuracy and reliable expansion for varmint hunting and target shooting applications. These precision-manufactured bullets feature Sierra's proven spitzer boat tail design that maintains velocity and trajectory stability at extended ranges.

What Makes This Different

The GameKing line utilizes Sierra's proprietary jacket design with controlled thickness variations to ensure uniform expansion while maintaining structural integrity. Unlike standard hunting bullets that may fragment or fail to expand consistently, the 1365 GameKing maintains 60-70% weight retention across impact velocities from 1,800 to 3,200 fps. The boat tail configuration reduces drag by approximately 6-8% compared to flat base designs, extending effective range and improving wind drift resistance.

Key Features

• 55-grain spitzer boat tail design optimized for .22 caliber rifles
• Controlled expansion jacket maintains 60-70% weight retention
• Boat tail base reduces drag and improves long-range ballistics
• 0.224" diameter with 0.015" jacket thickness tolerance
• Compatible with twist rates from 1:12" to 1:7"
• Ballistic coefficient of 0.235 for superior downrange performance
• Manufactured to +/- 0.3 grain weight consistency

Field performance testing demonstrates sub-MOA accuracy potential in quality rifle systems when properly loaded. The 55-grain weight provides optimal performance in standard .223 Remington and 5.56 NATO chambers with 20-24" barrel lengths. Expansion characteristics remain consistent across temperature ranges from -20°F to 120°F, making these bullets suitable for year-round hunting applications.
