Sierra 4440T Tipped GameKing 270 Win 140gr HPBT Bullets 50/Box

The Sierra 4440T Tipped GameKing delivers enhanced terminal performance for 270 Winchester hunters seeking consistent expansion and deep penetration on medium to large game. This 140-grain hollow point boat tail bullet features Sierra's precision-engineered polymer tip that initiates reliable expansion while maintaining aerodynamic efficiency downrange.

What Makes This Different

The polymer tip design sets the Tipped GameKing apart from traditional hollow point bullets by preventing tip deformation during magazine feeding and storage. This tip also lowers ballistic coefficient compared to standard GameKing bullets, improving long-range accuracy. The boat tail base reduces drag and wind drift, extending effective range beyond conventional flat-base designs.

Key Features

• 140-grain weight optimized for 270 Winchester ballistics and medium game hunting
• Polymer tip prevents deformation and enhances ballistic coefficient
• Hollow point boat tail (HPBT) design for controlled expansion and accuracy
• Jacket thickness engineered for 2,400-3,200 fps muzzle velocities
• Boat tail base reduces drag coefficient by approximately 6-8%
• 50-count bulk packaging for serious hunters and reloaders
• Compatible with standard 270 Winchester chamber specifications

Field performance shows reliable expansion at impact velocities between 1,800-3,000 fps, making this bullet effective from muzzle to extended hunting ranges. The controlled expansion characteristics work well on deer, elk, and similar-sized game where deep penetration and energy transfer are critical. Weather conditions have minimal effect on the polymer tip, maintaining consistent performance in temperature extremes from -20°F to 140°F.
