Design Highlights of Hornady Superformance 7mm-08 Remington Rifle Rounds
Hornady Ammunition incorporates advanced technological standards to produce centerfire rifle loads capable of delivering match-style accuracy and ethical game harvesting capability.
Monolithic Gilding Metal Construction
The Gilding Metal eXpanding bullet consists of a tough copper alloy that resists core-jacket separation upon high-velocity impact. Consequently, this solid construction retains over 95% of its original projectile weight, driving deep through heavy bone and thick muscle tissue to hit vital organs.
Polymer Tip & Aerodynamic Boat Tail Design
A hard polymer tip initiates rapid expansion upon impact while improving the bullet’s aerodynamic streamline in flight. Thus, the combination of a polymer tip and boat tail heel reduces downrange aerodynamic drag, providing flat trajectories and wind resistance out past 300 yards.
Superformance Propellant Technology
Hornady uses specialized progressive propellants that increase projectile speed without increasing peak chamber pressures. As a result, hunters achieve magnum-level velocities from standard rifle actions without experiencing harsh bolt lift or excessive barrel throat erosion.
To review industry pressure limits and rifle barrel tolerances, reference the official SAAMI Rifle Cartridge Technical Standards for detailed 7mm-08 Remington chambering rules.
