Hornady InterLock 7mm .284 139gr Spire Point Bullets - 100 Count

The Hornady InterLock 7mm .284 139 grain Spire Point bullets deliver consistent expansion and deep penetration for medium to large game hunting. These precision-engineered projectiles feature Hornady's proven InterLock ring technology that mechanically locks the core and jacket together during expansion.

What Makes This Different

The InterLock ring sets these bullets apart from conventional cup-and-core designs by preventing core-jacket separation during impact. While standard bullets can fragment or lose their core upon hitting bone or dense tissue, the InterLock system maintains bullet integrity for maximum weight retention. This translates to straighter wound channels and more reliable terminal performance across varying impact velocities.

Key Features

• InterLock ring mechanically locks core to jacket preventing separation
• 139 grain weight optimized for 7mm cartridges like 7mm-08 and .280 Remington
• Spire point design provides flat trajectory and rapid expansion
• Tapered jacket thickness controls expansion from tip to base
• Lead core engineered for 60-90% weight retention
• Secant ogive profile reduces drag for improved ballistic coefficient
• Consistent .284 diameter maintains tight tolerances for accuracy

Field testing demonstrates these bullets maintain structural integrity through heavy bone while creating adequate wound channels for quick, ethical harvests. The 139 grain weight provides excellent sectional density for penetration on deer, elk, and similar-sized game. Ballistic coefficient of approximately .486 delivers flat trajectory out to 400 yards with proper cartridge selection.
