Hornady InterLock 303 Cal .312 174gr RN Bullets 100/Box 3130

The Hornady 3130 InterLock bullets deliver consistent expansion and deep penetration for .303 caliber rifles. These 174-grain round nose 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 expanding to nearly twice its diameter. Standard hunting bullets often lose their cores upon impact, reducing penetration and terminal performance on medium to large game.

Key Features

• InterLock ring mechanically bonds core and jacket for controlled expansion
• 174-grain weight optimized for .303 British cartridge performance
• Round nose profile enhances feeding reliability in military surplus rifles
• .312 inch diameter designed for .303 caliber bore specifications
• Lead core construction provides consistent weight distribution
• Tapered jacket design controls expansion at various velocities
• 100 bullets per box with 15 boxes per case for bulk loading

These bullets perform effectively across velocity ranges from 2,200 to 2,600 fps, making them suitable for both military surplus rifles and modern sporting firearms. The round nose configuration feeds smoothly through magazine-fed actions while the 174-grain weight provides excellent sectional density for hunting deer, elk, and similar-sized game. The InterLock design maintains structural integrity through heavy bone and muscle tissue.
