Hornady InterLock 405 Caliber 300 Grain Spire Point Reloading Bullet

Hornady’s InterLock bullet incorporates a raised ring inside the jacket that embeds into the bullet’s core, locking the core and jacket together during expansion to maintain mass and energy retention. The tapered jacket features precisely controlled thickness engineered for consistent expansion across all velocities. The one-piece core resists separation, while the cannelure enables accurate and consistent crimping and works in conjunction with the InterLock ring to keep the core and jacket locked during expansion.
