Hornady InterLock 7mm 139 Grain Boat Tail Spire Point Reloading Bullet

The Hornady InterLock bullet incorporates a raised ring inside the jacket that embeds into the core, maintaining the bond between core and jacket during expansion to preserve mass and energy. Precise control of the tapered jacket thickness allows for consistent expansion across all velocities, while the one-piece core resists separation. A cannelure serves dual purposes: enabling accurate and consistent crimping while working in concert with the InterLock ring to keep the core and jacket locked together throughout the expansion process.
