Hornady InterLock 7mm, 284 Caliber (284 Diameter) Bullets 139 Grain Spitzer Boat Tail with Cannelure Box of 100

Overview

The Hornady InterLock 7mm (.284 diameter) 139-grain bullets are traditional soft-point boat-tail (BTSP) reloading projectiles engineered for big-game hunting and consistent accuracy. Featuring a ballistic coefficient of .453 and a sectional density of .246, these bullets incorporate Hornady's proprietary InterLock ring—a raised ridge embedded within the core that mechanically locks the one-piece core and tapered jacket together during expansion. This design prevents core-jacket separation, allowing the bullet to retain maximum mass, momentum, and energy for deep penetration and reliable wound channels. Strategic inner grooves weaken the upper jacket to ensure controlled expansion across various velocities, while the integrated cannelure provides consistent crimping. Each box contains 100 bullets.
