Hornady InterLock 7mm 139gr Boat Tail Spire Point

Hornady InterLock 7mm 139gr Boat Tail Spire Point Bullets

Hornady's InterLock bullet line represents a proven approach to reliable big game hunting ammunition. These 139-grain projectiles combine time-tested design principles with modern manufacturing to deliver consistent, predictable performance in the field.

Key Features

• InterLock Ring System: An embedded ring in the bullet's core locks the jacket and core together during expansion, preventing separation and maximizing retained mass and energy
• Tapered Jacket: Precisely controlled jacket thickness ensures consistent expansion across a wide velocity range, from close-range shots to extended distances
• One-Piece Core: Unlike divided-core designs, the solid core resists fragmentation and maintains structural integrity through impact
• Inner Grooves: Strategically positioned grooves weaken the upper jacket section to initiate controlled expansion while the InterLock ring maintains core integrity
• Boat Tail Design: Improves ballistic coefficient for flatter trajectory and better long-range performance
• Cannelure: Provides a secure crimping groove for handloaders and works in concert with the InterLock system

Performance

These bullets are engineered for hunters who demand reliability and ethical performance on big game. The combination of controlled expansion and weight retention creates a substantial wound channel while minimizing the risk of bullet failure or deflection. Whether you're handloading for precision or seeking factory ammunition built on proven bullet designs, the Hornady InterLock delivers the terminal performance serious hunters expect.
