Special Features

• InterLock ring is embedded in the core to mechanically lock jacket and core together, helping the bullet retain mass and energy throughout expansion.
• Inner grooves in the upper jacket strategically weaken that section, promoting consistent, controlled mushrooming even as velocity drops at longer ranges.
• Tapered jacket thickness is precisely tuned for expansion across a wide band of impact speeds, balancing strong upset with a solid shank for penetration.
• One-piece core design resists separation, supporting deep penetration and large, uniform wound channels on heavier-bodied game.
• Boat tail spire point profile provides an efficient, aerodynamic shape that supports flatter trajectories and stable flight from typical 30 caliber hunting rifles.

Practical Benefits

• Hornady InterLock 30 Cal .308 180 Grain Boat Tail Soft Point (3072) fits hunters who want a heavier 30 caliber bullet for elk, larger deer, and similar game in cartridges such as 308 Winchester and 30-06 Springfield.
• The 180 grain weight and .308 diameter geometry pair well with common big game twist rates, helping your loads hold energy and track predictably at extended field distances.
• High sectional density, controlled expansion, and strong weight retention work together to create deep-reaching wound channels, which supports quick, ethical harvests on larger animals.
• With 100 bullets per box, you can develop a trusted hunting load, confirm drops at multiple ranges, and still have enough projectiles for multiple seasons of serious big game hunting.
• If you want a traditional lead core 30 caliber hunting bullet optimized for penetration and reliability, Hornady InterLock 30 Cal .308 180 Grain Boat Tail Soft Point Bullets (3072) are a proven platform for medium and large game hunters.
