Hornady InterLock 7mm Bullets: Engineered for Hunting Performance
The Hornady InterLock bullet represents decades of hunting ammunition development, combining proven design principles with modern manufacturing precision. These 139-grain spire point projectiles are purpose-built for hunters who demand reliable, consistent performance on big game.
Core Design Features
InterLock Ring Technology The defining feature of this bullet is Hornady's proprietary InterLock ring—a raised band embedded directly in the bullet's core. This mechanical lock keeps the jacket and core unified during expansion, preventing separation and ensuring maximum weight retention. A bullet that holds together delivers more energy to the target and creates a more effective wound channel.
Controlled Expansion The tapered jacket is manufactured to exacting tolerances, with thickness precisely controlled from tip to base. This design ensures reliable expansion across a wide velocity range—whether you're shooting at close range or extending your shot to moderate distances. You get consistent performance regardless of your specific load or hunting situation.
One-Piece Construction Unlike bullets with divided cores, the InterLock features a solid, one-piece core that cannot separate. This engineering choice directly translates to better weight retention and more consistent ballistic performance downrange.
