.300 Weatherby Magnum 180gr Hornady Interlock 20/Box offers strategic accuracy and flat shooting, made for delivering long range lethal power, and ultra high velocity. This ammunition utilizes Hornady Interlock bullets, which feature exposed lead tips for controlled expansion and hard-hitting terminal performance. The Interlock soft point bullet also features Hornady’s pioneering secant ogive design and exclusive InterLock ring. The raised ring inside the jacket is embedded in the bullet’s core which keeps the core and jacket locked together during expansion to retain mass and energy. This ammunition is built for hunting medium sized game (50 to 300 lbs) including whitetail deer, and for hunting large game (300 to 1500 lbs), including elk. This ammunition is new production, non-corrosive, boxer primed, in reloadable brass cases.
