Hornady 405 Cal .411 300 gr InterLock® SP

Our traditional line of bullets feature exposed lead tips for controlled expansion and hard‑hitting terminal performance. Most have our pioneering secant ogive design — one of the most ballistically efficient profiles ever developed (see diagram to right). Most feature our exclusive 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.

Features

• Inner Grooves: Strategically weaken the upper section of the jacket, ensuring consistent, controlled expansion, even at long range.
• Tapered Jacker: 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.
• 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.
