The Hornady InterLock .30 Cal 165Gr SP Rifle Bullets feature exposed lead tips for controlled expansion and hard-hitting terminal performance. They feature a pioneering secant ogive design - one of the most ballistically efficient profiles ever developed. The InterLock design - a raised ring inside the jacket that is embedded in the bullet's core that keeps the core and jacket locked together during expansion to retain mass and energy.

• Inner grooves strategically weaken the upper section of the jacket, ensuring consistent, controlled expansion, even at long range
• Tapered jacket thickness is precisely controlled for expansion at all velocities
• One-piece core does not separate like two-piece divided cores. The InterLock retains more mass and energy for deep penetration and large, consistent wound channels that ensure quick, clean kills
• Cannelure provides accurate and consistent crimping and also works with InterLock ring to ensure the core and jacket remain locked during expansion
• The raised InterLock ring is embedded in the bullet's core, ensuring the core and jacket are locked in one piece during expansion to retain mass and energy
