Sierra 4665T Tipped GameKing .308 Cal 165GR Bullets - 50/Box

The Sierra 4665T Tipped GameKing delivers exceptional terminal performance for hunters pursuing medium to large game with .308 caliber rifles. This 165-grain bullet combines Sierra's proven GameKing design with a polymer tip for improved ballistic coefficient and controlled expansion.

What Makes This Different

The polymer tip initiates rapid expansion while the tapered jacket ensures controlled weight retention through heavy bone and muscle. Unlike standard soft-point bullets, the aerodynamic tip maintains velocity downrange and provides flatter trajectory. Sierra's proprietary jacket thickness varies from base to tip, creating predictable mushrooming that transfers maximum energy to the target.

Key Features

• 165-grain weight optimized for .308 Winchester and similar cartridges
• Polymer tip enhances ballistic coefficient and initiates expansion
• Tapered jacket design ensures 60-70% weight retention
• Boat-tail base reduces drag and improves long-range accuracy
• Lead core bonded to jacket prevents separation on impact
• Proven GameKing profile trusted by hunters for decades
• 50 bullets per box for extended shooting sessions

Field testing demonstrates consistent 1.5-2 MOA accuracy in quality bolt-action rifles when properly loaded. The 165-grain weight provides excellent versatility for deer, elk, and similar-sized game at ranges from 100 to 400 yards. Expansion begins immediately upon impact while the heavy base penetrates deeply through vital organs. The bullet performs reliably in various weather conditions and maintains accuracy across temperature extremes.
