The Frontier Cartridge FR310 delivers military-grade precision with 68-grain hollow point boat tail projectiles engineered for match-grade accuracy in 5.56x45mm NATO chambered rifles. This premium centerfire ammunition combines consistent powder charges with carefully selected components to achieve tight groupings at extended ranges. Competition shooters and precision rifle enthusiasts rely on this ammunition for its repeatable performance and quality construction.
What Makes This Different
The 68-grain HPBT design provides superior ballistic coefficient compared to standard 55-grain FMJ rounds, maintaining velocity and reducing wind drift at longer distances. Frontier's military-grade manufacturing standards ensure consistent case dimensions and powder charges within tight tolerances. The boat tail configuration reduces drag and improves stability, while the hollow point design enhances accuracy through better weight distribution and aerodynamic properties.
