BAGGED not BOXED. Backed by a solid guarantee and proven for high performance, Hornady InterLock Bullets are ideal for big game hunting. Some of the features appreciated most by seasoned hunters is the polymer tip that produces a flat and exceptionally fast bullet, one-piece core and jacket design, outstanding weight retention, and controlled expansion. These bullets also feature the trademarked InterLock ring system. With this, the core and jacket of the bullet stay firmly locked in place during expansion. The outcome is a more massive wound channel, ensuring a clean, one-shot kill of even the toughest game.
