Hornady InterLock 308 Winchester 170 Grain Rifle Ammunition

Hornady’s InterLock bullet design incorporates a raised ring inside the jacket that embeds into the bullet’s core, locking the core and jacket together during expansion to preserve mass and energy. The tapered jacket has precisely controlled thickness to achieve consistent expansion across all velocity ranges, while the one-piece core resists separation. A cannelure serves dual purposes: it enables accurate and consistent crimping while working in concert with the InterLock ring to maintain core-jacket integrity throughout expansion.
