The Remington Core-Lokt Tipped 7mm-08 Remington ammo bridges the gap between the original Core-Lokt’s field-proven terminal performance and modern ballistic polymer tip technology. For hunters who demand both long-range accuracy and reliable expansion on medium-to-large game, this 140-grain polymer tip load delivers 2860 feet per second muzzle velocity and 2542 foot-pounds of energy. The 7mm-08 Remington cartridge itself is a necked-down .308 Winchester case, offering flatter trajectory and lighter recoil than its parent while maintaining serious downrange punch. You’re looking at a round that shoots flat to 300 yards, expands consistently across a wide velocity window, and comes from a Remington factory with a century of big-game load development behind it.
Built for the Box
Remington engineers the Core-Lokt Tipped bullet with a rearward center of gravity, improving in-flight stability and accuracy. The polymer tip initiates expansion on impact, even at extended ranges where velocity has bled off. Behind that tip sits the original Core-Lokt jacket—a mechanically locked lead core that holds together through hide, bone, and muscle. Factory-fresh brass cases are boxer-primed, non-corrosive, and reload easily when you’re ready to work up a custom load for your rifle.
