The Hornady InterLock Bulk Bullets in 7.62x39mm, .310 inch, 123 grain soft point (brand part no. HDY3140B), are a proven big-game hunting bullet backed by decades of performance in one of the most widely loaded rifle calibers. Hornady builds these bullets around the trademarked InterLock ring system, which mechanically locks the core and jacket together so they stay firmly in place during expansion instead of separating on impact. The result is a more massive, controlled wound channel and consistent, one-shot performance on big game. This bulk bullet ships bagged rather than boxed, sized for reloaders who load 7.62x39mm in real volume.
