Sierra MatchKing 22 Cal 77gr HPBT Bullets 250ct - Model 9377MP

The Sierra MatchKing 9377MP delivers exceptional accuracy for competitive shooters and precision enthusiasts demanding match-grade performance from their .22 caliber rifles. These 77-grain hollow point boat tail bullets represent decades of Sierra's ballistic engineering expertise, specifically designed for long-range accuracy and consistent performance.

What Makes This Different

Unlike standard hunting bullets, the MatchKing features Sierra's precision-manufactured hollow point design that creates a favorable center of gravity for enhanced stability in flight. The boat tail configuration reduces drag by approximately 6-8% compared to flat-base bullets, extending effective range and maintaining velocity downrange. Each bullet undergoes strict quality control measures, with weight variations held to ±0.3 grains for lot-to-lot consistency.

Key Features
