Hornady InterLock 270 Cal .277 140gr BTSP Bullets - 100 Count

The Hornady 2735 InterLock bullets deliver proven expansion and weight retention for consistent terminal performance on medium to large game. These .277 caliber 140-grain boat tail spire point projectiles feature Hornady's signature InterLock ring that mechanically locks the core and jacket together during expansion.

What Makes This Different

The InterLock ring technology sets these bullets apart from conventional cup-and-core designs by preventing jacket-core separation during impact. This mechanical bond ensures the bullet maintains its weight and structure through tough hide, bone, and tissue. Independent testing shows InterLock bullets retain 85-95% of their original weight compared to 60-75% for standard hunting bullets.

Key Features

• InterLock ring mechanically locks jacket to lead core for controlled expansion
• 140-grain weight optimized for .270 Winchester and similar cartridges
• Boat tail design reduces drag for flatter trajectory and retained velocity
• Spire point initiates rapid expansion on impact with game animals
• Tapered jacket thickness controls expansion rate from tip to base
• Cannelure provides consistent seating depth and roll crimp retention
• Bulk packaging of 100 bullets reduces cost per round for volume reloaders

Field performance demonstrates reliable expansion at velocities from 1,800 to 3,000 fps, making these bullets suitable for various .270 caliber cartridges. The 140-grain weight provides excellent sectional density for deep penetration on deer, elk, and similar-sized game. Weather-resistant construction maintains accuracy in temperature extremes from -20°F to 140°F.
