Special Features
- InterLock ring is a raised band embedded directly into the bullet core, mechanically locking the jacket and core together throughout expansion to retain mass and momentum and prevent the core-jacket separation that reduces 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 translates to consistent expansion and deep, straight-line wound channels.
- 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 wide range of 7mm cartridges and hunting distances.
- Secant ogive profile combines a slender exposed lead point with a long bearing surface, producing lower drag, improved in-flight stability, flatter trajectories, and greater accuracy compared to traditional round nose hunting bullet designs.
- 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.
Practical Benefits
- The 175 grain weight gives you a heavy, high sectional density 7mm bullet that drives deep through the large muscle masses and heavy bone of elk, moose, and black bear, making it a natural fit for hunters who prefer a slower, heavier projectile over lighter, faster options.
- The InterLock construction keeps core and jacket together when the bullet encounters hard resistance, giving you the full energy transfer and penetration that anchors large animals cleanly rather than leaving a spent jacket and a deflected core.
- Compatible with any cartridge using a .284 diameter projectile, including 7mm Remington Magnum, 7mm-08 Remington, 280 Ackley Improved, 7mm WSM, 7mm Weatherby Magnum, 7mm STW, and 7mm PRC, making this a highly versatile hunting component across the full 7mm family.
- The tapered jacket and interior groove design work across the full 2,000 to 3,300 fps velocity range, so this bullet performs whether you are loading a mild 7mm-08 or a hard-driving 7mm Remington Magnum without needing a separate bullet for each platform.
- The secant ogive and long bearing surface give you the accuracy at the bench that carries over to consistent field performance, whether your shot comes at 100 yards in timber or stretches past 300 yards across open terrain.
- For the reloader who values a proven traditional design over newer premium options, your load built around the Hornady InterLock SP (2850) delivers the deep penetration and reliable expansion that hunters have trusted for decades on the largest North American game.
The Hornady InterLock SP (2850) 7mm .284 diameter 175 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.
