Remington Core-Lokt 7mm Remington Magnum ammo in 150-grain jacketed soft point configuration has been the go-to big-game load since the cartridge’s introduction in 1962. The Core-Lokt bullet design uses a progressively tapered copper jacket mechanically locked to a solid lead core, delivering controlled expansion on impact while retaining enough mass to reach vitals through bone and heavy tissue. At 3110 fps muzzle velocity and 3221 ft-lbs of energy, this 150-grain load flattens trajectory out to 300 yards and carries sufficient momentum for elk, moose, and bear-size game.
Built for the Box
Each round starts with a Boxer-primed brass case loaded to SAAMI specifications. The jacketed soft point bullet features an exposed lead tip that initiates expansion on contact, while the copper jacket peels back in controlled petals rather than fragmenting. Remington has manufactured Core-Lokt ammunition continuously since 1939, and the 7mm Remington Magnum chambering pairs the bullet’s proven terminal performance with the magnum case’s extended effective range. Non-corrosive primer and powder formulation make this ammunition suitable for hunting in wet conditions and long-term storage.
