Hornady InterLock 30 Cal .308 180gr BTSP Bullets - 100 Count Box

The Hornady 3072 InterLock bullets deliver consistent expansion and weight retention for reliable terminal performance in .30 caliber rifles. These 180-grain boat tail 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. This mechanical bond ensures the bullet retains 70-80% of its original weight while expanding to nearly twice its diameter. The boat tail design reduces drag for flatter trajectories and improved long-range accuracy compared to flat-base bullets.

Key Features

• InterLock ring mechanically locks jacket to lead core for controlled expansion
• 180-grain weight optimized for medium to large game hunting applications
• Boat tail design improves ballistic coefficient and downrange performance
• Spire point tip initiates rapid expansion upon impact
• Tapered jacket thickness controls expansion rate and penetration depth
• Compatible with all .308 diameter rifle cartridges (.30-06, .308 Win, .300 Win Mag)
• Bulk 100-count packaging reduces per-round cost for high-volume shooters

These bullets excel in hunting scenarios where deep penetration and reliable expansion are critical. The 180-grain weight carries sufficient energy for elk, deer, and black bear at extended ranges while maintaining accuracy potential under 1.5 MOA in quality rifle systems. The boat tail configuration maintains velocity better than flat-base designs, extending effective range by 50-75 yards in typical hunting cartridges.
