Hornady InterLock 25 Cal .257 117gr Round Nose Bullets 100/Box

The Hornady 2550 InterLock bullets deliver consistent expansion and deep penetration for medium game hunting applications. These .257 caliber projectiles feature the proven InterLock ring design that mechanically locks the core and jacket together during expansion.

What Makes This Different

The InterLock ring system sets these bullets apart from conventional cup-and-core designs by preventing core-jacket separation during impact. This mechanical bond ensures the bullet retains 75-85% of its original weight while creating a controlled mushroom shape. The 117-grain round nose profile provides excellent penetration through brush and delivers reliable performance on deer-sized game at moderate velocities.

Key Features

• InterLock ring mechanically locks core to jacket for controlled expansion
• 117-grain weight optimized for .25-06 Remington and .257 Roberts cartridges
• Round nose profile reduces deflection in brush and light cover
• Lead core with tapered jacket design for consistent mushrooming
• Cannelured shank provides secure case mouth crimping
• 100 bullets per box for extended shooting sessions
• Sectional density of .253 delivers excellent penetration characteristics

These bullets perform effectively at velocities between 2,400-3,000 fps, making them suitable for both moderate and high-intensity loads. The round nose configuration excels in dense timber hunting situations where brush deflection is a concern. Hunters report consistent performance on whitetail deer, antelope, and similar-sized game at ranges from 50 to 300 yards.
