More Details About This Magtech 77gr HPBT 5.56x45 Ammo
This 5.56x45 round represents a great partnership between two of the ammunition industry’s heaviest hitters: Magtech, the commercial brand of the truly enormous CBC Group, and Sierra, the Missourian company which for 60 years has strived to make the world’s most accurate projectiles. Everything about this round is designed to give your AR-15 match grade accuracy, which it owes largely to its 77 grain MatchKing bullet.

The MatchKing’s jacket is so concentric that it’s virtually perfectly so, and each bullet in this case weighs essentially identical to one another. This bullet is equipped with a cannelure, which serves to prevent deleterious setback from occurring. The MatchKing’s boat tail design causes it to produce very little turbulence behind it, acting to flatten its trajectory and preserve its velocity downrange. Finally, the bullet’s hollow point meplat helps greatly to prevent wind deflection.

Magtech’s brass casing is fresh from the factory, with consistent dimensions and the strength for multiple reloads. This cartridge’s clean burning propellant will preserve your rifle’s accuracy over the course of a long shooting session, and its primer is non-corrosive as well.
