The Hornady InterLock .30 Cal 165Gr SP Rifle Bullets feature exposed lead tips for controlled expansion and hard-hitting terminal performance. They feature a pioneering secant ogive design - one of the most ballistically efficient profiles ever developed. The InterLock design - 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. Inner grooves strategically weaken the upper section of the jacket, ensuring consistent, controlled expansion, even at long range Tapered jacket thickness is precisely controlled for expansion at all velocities One-piece core does not separate like two-piece divided cores. The InterLock retains more mass and energy for deep penetration and large, consistent wound channels that ensure quick, clean kills Cannelure provides accurate and consistent crimping and also works with InterLock ring to ensure the core and jacket remain locked during expansion The raised InterLock ring is embedded in the bullet's core, ensuring the core and jacket are locked in one piece during expansion to retain mass and energy #html-body [data-pb-style="62DF828A82D7C"]{justify-content: flex-start; display: flex; flex-direction: column; background-position: left top; background-size: cover; background-repeat: no-repeat; background-attachment: scroll; border-style: none; border-width: 1px; border-radius: 0px; margin: 0px 0px 10px; padding: 10px;}#html-body [data-pb-style="62DF828A82D89"]{border-style: none; border-width: 1px; border-radius: 0px; margin: 0px; padding: 0px;}
