Hornady InterLock 25 Cal .257 117gr BTSP Bullets - 100 Count Box

The Hornady InterLock 25 caliber .257 117 grain boat tail spire point bullets deliver exceptional accuracy and controlled expansion for medium game hunting. These precision-manufactured 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. This mechanical bond ensures the bullet retains 80-90% of its original weight while creating a controlled mushroom shape. The boat tail design reduces drag and improves ballistic coefficient compared to flat-base bullets, extending effective range and maintaining velocity downrange.

Key Features

• InterLock ring mechanically bonds core and jacket for controlled expansion
• 117 grain weight optimized for .25 caliber cartridges like .25-06 and .257 Roberts
• Boat tail design improves ballistic coefficient and long-range performance
• Spire point tip initiates rapid expansion on impact
• Lead core with gilding metal jacket for consistent performance
• Precision manufacturing ensures consistent bullet-to-bullet dimensions
• 100 bullets per box provides excellent value for reloaders

These bullets excel in hunting applications from whitetail deer to antelope at ranges from 100 to 400 yards. The 117 grain weight provides an ideal balance of velocity and energy retention for .25 caliber cartridges. Field testing shows consistent 1.5-2 MOA accuracy in quality rifles with proper load development. The InterLock design performs reliably across impact velocities from 1,800 to 3,000 fps, making it suitable for various cartridge applications.
