Sierra 1820 GameKing 270 Winchester 130gr Spitzer Boat Tail Bullets

The Sierra 1820 GameKing delivers consistent expansion and deep penetration for medium to large game hunting. This 130-grain spitzer boat tail design combines accuracy with reliable terminal performance across various hunting conditions.

What Makes This Different

The GameKing's tapered jacket construction provides controlled expansion while maintaining weight retention superior to standard cup-and-core bullets. Sierra's precision manufacturing process ensures uniform bullet weight within 0.3 grains and concentricity tolerances that exceed industry standards. The spitzer boat tail profile reduces drag coefficient by 15% compared to flat-base designs, extending effective range and maintaining velocity downrange.

Key Features

• 130-grain weight optimized for 270 Winchester ballistics and game from deer to elk
• Spitzer boat tail design with 0.496 ballistic coefficient for flat trajectory
• Tapered jacket construction engineered for 60-80% weight retention
• Precision-formed lead core bonded to gilding metal jacket
• Consistent ogive profile maintains concentricity within 0.0015 inches
• Factory-sorted for uniform weight distribution across the entire lot
• 100-count packaging reduces per-round cost for volume reloaders

Field performance data shows the GameKing maintains over 1,800 fps velocity at 300 yards when loaded to standard specifications. The bullet initiates expansion at impact velocities as low as 1,600 fps, making it effective for longer shots on medium game. Hunters report clean pass-throughs on broadside shots with adequate blood trails, while quartering shots demonstrate the bullet's ability to penetrate heavy bone and muscle.
