Hornady InterLock projectiles offer exposed lead tips for controlled expansion and effective terminal performance. Many feature the pioneering secant ogive design, one of the most ballistically efficient profiles ever developed. Most also incorporate the exclusive InterLock® design, a raised ring inside the jacket that is embedded in the bullet's core. This design keeps the core and jacket locked together during expansion, helping 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: Jacket thickness is precisely controlled for expansion at all velocities.
• One-Piece Core: Designed not to separate like two-piece divided cores. The InterLock® retains more mass and energy for deep penetration and large, consistent wound channels.
• Cannelure: Provides accurate and consistent crimping and works with the InterLock® ring to ensure the core and jacket remain locked during expansion.
• InterLock® Ring: 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.

Secant Ogive Design

Pioneered by Hornady for use in hunting projectiles, this technology advanced ballistic engineering and is now utilised in projectiles for various shooting disciplines, from match to varmint applications. The secant ogive is a geometrically developed design that creates a ballistically efficient profile, while retaining an optimum bearing surface. This combination of a slender point and increased bearing surface results in lower drag, enhanced stability, flatter trajectories, and impressive accuracy.
