Gorilla 223 Remington 77 Grain Sierra MatchKing ammunition delivers match-grade precision built on factory-new brass, competition-grade primers, and carefully selected projectiles. This load achieves 2,540 feet per second velocity, making it the standard choice for precision rifle shooters who demand sub-minute-of-angle accuracy at distance. Each box contains 20 rounds optimized for consistent ballistic performance across strings of fire.
The 77-grain Sierra MatchKing bullet is purpose-built for long-range stability and energy retention. At 2,540 fps from standard .223 Remington platforms, this velocity window maximizes the ballistic coefficient advantages of the heavier projectile while maintaining reliable feeding and function in both semi-automatic and bolt-action rifles. Gorilla Ammunition's commitment to component selection—factory-fresh cases, match-grade primers, and premium Sierra projectiles—eliminates variables that degrade group size and shot-to-shot consistency, critical factors in competitive and precision applications where tenth-of-inch differences determine placement.
This cartridge serves competitive shooters, precision rifle enthusiasts, and long-range training communities. Whether at 100 yards on the prone line, 300 yards in field competition, or extended-range practice, the 77-grain load provides the trajectory stability and minimal wind deflection needed to hold competitive scores. The heavier bullet design also delivers superior penetration characteristics for full-value target interaction, an advantage in both precision competition and field scenarios where reliable energy transfer matters.
Match-grade ammunition sits at the premium tier of .223 Remington offerings. The 77-grain Sierra MatchKing configuration has been the baseline reference for precision rifle standards for decades, proven in service rifle competitions and long-range disciplines. Gorilla's factory-new brass and match-primer specifications ensure that ammunition performance remains constant across multiple firings and reloading cycles, a requirement for shooters tracking velocity ES and SD as part of their ballistic development.
