Hornady InterLock 270 Cal .277 150gr Spire Point Bullets 100ct

The Hornady InterLock .270 caliber bullets deliver consistent expansion and deep penetration for medium to large game hunting. These 150-grain spire point 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 jacket-core separation during impact. While standard bullets can lose their core upon expansion, the InterLock's raised ring around the bullet's midsection creates a mechanical bond that maintains weight retention up to 90%. This translates to deeper penetration and more reliable terminal performance on game animals.

Key Features

• InterLock ring prevents jacket-core separation for maximum weight retention
• 150-grain weight optimized for .270 Winchester and similar cartridges
• Spire point design provides flat trajectory and rapid expansion
• Tapered jacket thickness controls expansion from tip to base
• Lead core precisely swaged for consistent density and balance
• Cannelure groove allows proper bullet seating and crimp
• 100 bullets per box with consistent .277 diameter sizing

Field performance shows these bullets maintain their structural integrity through heavy bone and muscle tissue. The spire point initiates expansion quickly upon impact while the InterLock ring ensures the expanded bullet retains sufficient mass for complete penetration. Hunters report clean pass-throughs on deer-sized game and reliable performance on elk and similar large game when placed properly.
