Hornady built the .30 Cal/.308 180 gr InterLock Boat Tail Spire Point bullet (Hornady part no. 3072) around a simple idea: keep the jacket and core mechanically locked together so the bullet retains mass through expansion. A raised InterLock ring inside the jacket is embedded directly into the core, the tapered jacket controls expansion at different velocities, and the cannelure locks in a consistent crimp for reliable feeding.
