Sierra GameKing 7mm 140gr HPBT Bullets - 100 Count Box #1912

The Sierra 1912 GameKing delivers consistent expansion and deep penetration for medium to large game hunting applications. This 140-grain hollow point boat tail bullet combines Sierra's proven GameKing design with precision manufacturing to provide reliable terminal performance across various hunting scenarios.

What Makes This Different

The GameKing's hollow point design creates controlled expansion while the boat tail configuration maintains velocity and reduces wind drift at extended ranges. Sierra's jacket thickness varies along the bullet length, with a thinner nose section for reliable expansion and a thicker base for weight retention. This design outperforms standard soft point bullets in both accuracy and terminal effectiveness, particularly on deer-sized game at ranges beyond 200 yards.

Key Features

• 140-grain weight optimized for 7mm cartridges including 7mm-08, 280 Remington, and 7mm Remington Magnum
• Hollow point boat tail (HPBT) design for controlled expansion and flat trajectory
• Tapered jacket construction ensures 60-70% weight retention after impact
• Boat tail base reduces drag coefficient by approximately 15% compared to flat base bullets
• Match-grade manufacturing with weight variance under 0.3 grains per bullet
• Sectional density of .248 provides excellent penetration on medium game
• 100-count bulk packaging for serious hunters and competitive shooters

Field testing demonstrates consistent 1.5-2 MOA accuracy in quality hunting rifles when properly loaded. The 140-grain weight provides optimal performance in standard twist rates while generating sufficient energy for ethical harvests on whitetail, mule deer, and similar-sized game out to 400 yards. The boat tail design maintains supersonic velocity longer than conventional bullets, extending effective range in magnum cartridges.
