Sierra 9377T MatchKing 22 Cal 77gr HPBT Bullets 50/Box

The Sierra 9377T MatchKing delivers match-grade accuracy with its precision-manufactured 77-grain hollow point boat tail design. These competition-proven bullets consistently produce sub-MOA groups at extended ranges, making them the preferred choice for serious precision shooters and competitive marksmen.

What Makes This Different

Sierra's MatchKing line features a unique hollow point design that shifts the center of gravity rearward for enhanced stability during flight. The boat tail configuration reduces drag coefficient by approximately 15% compared to flat base bullets, extending effective range and maintaining velocity. Each bullet undergoes strict quality control with weight variations held to ±0.3 grains, ensuring consistent ballistic performance shot after shot.

Key Features

• 77-grain hollow point boat tail design optimized for .22 caliber rifles
• Precision-drawn copper jacket with uniform wall thickness
• Lead core swaged to exact specifications for consistent weight distribution
• Ballistic coefficient of 0.362 for superior long-range performance
• Compatible with 1:7 and 1:8 twist rate barrels
• Match-grade manufacturing tolerances for competition accuracy
• 50-count packaging for convenient range sessions

Field testing demonstrates consistent 0.5-0.75 MOA accuracy in quality bolt-action rifles with proper handloading techniques. The 77-grain weight provides excellent performance in AR-15 platform rifles with appropriate twist rates, making it suitable for both precision rifle competitions and varmint hunting applications. Wind deflection remains minimal out to 600 yards due to the high ballistic coefficient and aerodynamic profile.
