Hornady 3120 InterLock 303 Cal .312 150gr SP Bullets 100/Box

The Hornady 3120 InterLock delivers consistent expansion and deep penetration for .303 British rifles, making it a proven choice for medium to large game hunting. This 150-grain soft point bullet features 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 soft points by preventing core-jacket separation even at high velocities. While standard soft points may fragment or lose their core upon impact, the InterLock design maintains bullet integrity for maximum weight retention. This translates to deeper penetration and more reliable terminal performance on game animals weighing 100-400 pounds.

Key Features

• InterLock ring mechanically bonds core to jacket for controlled expansion
• .312 diameter optimized for .303 British rifle chambers
• 150-grain weight provides excellent sectional density for penetration
• Soft point design initiates expansion on impact while retaining mass
• Tapered jacket thickness controls expansion rate and depth
• 100 bullets per box, 15 boxes per case (1,500 total bullets)
• Consistent manufacturing tolerances for accuracy and reliability

Field performance demonstrates the InterLock's effectiveness across various hunting scenarios. The 150-grain weight handles medium game like deer and antelope at typical .303 British velocities of 2,400-2,500 fps, while providing sufficient penetration for larger game like elk when shot placement is precise. The bullet's aerodynamic profile maintains stability at extended ranges, making it suitable for both brush hunting and open country shots.
