Sierra 1560 GameKing 6mm 100gr Spitzer Boat Tail Bullets 100/Box

The Sierra 1560 GameKing delivers consistent accuracy and reliable expansion for medium game hunting with its proven 6mm 100-grain design. This spitzer boat tail bullet combines Sierra's renowned manufacturing precision with aerodynamic efficiency for flat trajectories and dependable terminal performance.

What Makes This Different

The GameKing features Sierra's proprietary jacket design that maintains structural integrity through controlled expansion, unlike standard hunting bullets that may fragment unpredictably. The boat tail configuration reduces drag by approximately 15% compared to flat-base bullets, extending effective range and maintaining velocity downrange. Sierra's consistent manufacturing tolerances ensure shot-to-shot uniformity that competitive shooters and hunters depend on for critical accuracy.

Key Features

• 100-grain spitzer boat tail design optimized for 6mm/.243 caliber rifles
• Tapered jacket construction promotes controlled expansion at hunting velocities
• Boat tail base design reduces drag coefficient for improved ballistic performance
• Lead core bonding prevents jacket separation during expansion
• Consistent weight tolerance within ±0.3 grains for precision accuracy
• Compatible with standard 6mm cartridges including .243 Winchester and 6mm Creedmoor
• Manufactured in Sierra's ISO-certified facility with strict quality controls

Field testing demonstrates the GameKing's effectiveness on deer-sized game at ranges extending to 400 yards, with reliable expansion at impact velocities above 1,800 fps. The aerodynamic profile maintains supersonic flight longer than conventional bullets, reducing wind drift in crosswind conditions. Hunters report consistent performance across temperature ranges from -20°F to 100°F without velocity variations that affect point of impact.
