Sierra 1920 GameKing 7mm 160gr Spitzer Boat Tail Bullets 100/Box

The Sierra 1920 GameKing delivers exceptional accuracy and terminal performance for medium to large game hunting with its proven 160-grain spitzer boat tail design. This bullet combines Sierra's precision manufacturing with aerodynamic efficiency for consistent downrange ballistics. Hunters rely on the GameKing series for reliable expansion and deep penetration across various hunting scenarios.

What Makes This Different

The spitzer boat tail configuration reduces drag coefficient by approximately 15% compared to flat-base designs, extending effective range and maintaining velocity downrange. Sierra's jacket design features controlled thickness variations that promote uniform expansion while retaining 65-75% of original weight. The lead core bonding process ensures consistent performance shot after shot, distinguishing it from standard cup-and-core bullets that may fragment unpredictably.

Key Features

• 160-grain weight optimized for 7mm cartridges from .280 Remington to 7mm Remington Magnum
• Spitzer boat tail profile with 0.493 ballistic coefficient for flat trajectory
• Tapered jacket construction promotes controlled expansion at velocities from 1,800-3,000 fps
• Lead antimony core provides consistent weight retention and penetration
• Precision swaged construction maintains concentricity within 0.0003 inches
• 100-count bulk packaging reduces per-round cost for serious hunters
• Compatible with standard 7mm reloading dies and powder charges

Field performance demonstrates reliable expansion on game from whitetail deer to elk at ranges extending beyond 400 yards. The 160-grain weight provides sufficient sectional density for deep penetration while maintaining flat trajectory characteristics essential for longer shots. Temperature stability remains consistent from sub-freezing conditions to summer heat, maintaining point of impact reliability across hunting seasons.
