Hornady 3090 InterLock 30 Cal .308 220 gr Round Nose

Hornady’s InterLock bullet features a raised ring inside the jacket that is embedded in the bullet’s core that keeps the core and jacket locked together during expansion to retain mass and energy. The tapered jacket thickness is precisely controlled for expansion at all velocities, while its one-piece core does not separate. The cannelure provides accurate and consistent crimping and also works with the InterLock ring to ensure the core and jacket remain locked during expansion.
