Special Features

• InterLock ring is a raised band embedded directly into the bullet core, mechanically locking the jacket and core together throughout the expansion process to retain mass and momentum and prevent the core-jacket separation that limits penetration on heavy game.
• One-piece lead core eliminates the performance inconsistencies of two-piece divided core designs, delivering uniform density and mass distribution that produces consistent expansion and deep, straight-line wound channels on every impact.
• Strategically placed interior grooves weaken the upper jacket section in a controlled pattern, ensuring consistent, repeatable expansion across the full recommended velocity range from close-range shots to long-range field distances.
• Precisely tapered jacket controls expansion at high velocity while still promoting reliable upset at lower impact velocities, making this bullet a dependable performer across a broad family of 30 caliber cartridges.
• Cannelure provides an accurate and consistent crimp location and works in combination with the InterLock ring to further secure core-jacket integrity throughout the terminal phase.
• Secant ogive profile delivers lower drag, improved in-flight stability, and greater accuracy compared to traditional round nose hunting bullet designs of the same caliber and weight.

Practical Benefits

• The 165 grain weight sits in the sweet spot of the 30 caliber lineup, giving you a bullet that balances velocity, trajectory, and terminal momentum across cartridges ranging from 308 Winchester to 300 Winchester Magnum for deer, elk, black bear, and similar game.
• The InterLock construction keeps core and jacket together when the bullet encounters hard bone and heavy muscle, giving you the full energy transfer and penetration that anchors large game cleanly rather than leaving a spent jacket and a deflected core.
• Compatible with any cartridge using a .308 diameter projectile, including 308 Winchester, 30-06 Springfield, 300 Winchester Magnum, 300 WSM, 300 PRC, 30-06 Springfield, and 300 Rem Ultra Mag, making this one of the most versatile hunting bullets available across the full 30 caliber family.
• The tapered jacket and interior groove design work together across a wide velocity window, so this bullet performs whether you are loading a mild 308 Winchester for timber hunting or a hard-driving 300 Winchester Magnum for open-country shots without needing a separate component for each platform.
• For the reloader who values a proven traditional design, your load built around the Hornady InterLock SP (3040) delivers the deep penetration and reliable expansion that hunters have trusted for decades on North American big game.

The Hornady InterLock SP (3040) 30 Cal .308 diameter 165 grain is a solid fit for the experienced reloader and big game hunter who wants a dependable, traditionally designed cup and core hunting bullet that expands consistently, penetrates deeply, and holds together when it matters most in the field.
