The Remington Core-Lokt 280 Remington 150-grain jacketed soft point remains the reference standard for deer, elk, and black bear hunters who demand predictable terminal performance across varied shot angles and distances. Chambered in 280 Remington, this load generates 2890 feet per second at the muzzle and delivers 2781 foot-pounds of energy — enough to drive the 150-grain projectile through shoulder blades and rib cages while maintaining a controlled expansion profile that maximizes wound channel diameter without fragmenting. The Core-Lokt design locks a progressively tapered copper jacket to a solid lead core, preventing jacket-core separation during impact and retaining up to 95% of original bullet weight in typical game media.
Performance at a Glance
Remington engineers the Core-Lokt projectile with a mechanically bonded jacket that resists the centrifugal forces of barrel rifling and the hydrostatic shock of tissue penetration. At 2890 fps, this 150-grain bullet delivers a flat trajectory to 250 yards, dropping approximately 3.2 inches at 200 yards when zeroed at 100. The jacketed soft point nose cavity initiates expansion within the first two inches of penetration, mushrooming to roughly 1.6× original diameter in ballistic gelatin while the bonded core holds the expanded petals together. Boxer-primed brass cases eject cleanly and resize without work-hardening, supporting five or more reload cycles with standard dies.

This load suits bolt-action and semi-automatic rifles chambered in 280 Remington, including Remington Model 700, Browning X-Bolt, and Ruger Hawkeye platforms. Verify chamber specifications and magazine length before ordering — some short-action conversions may require bullet seating adjustments that fall outside factory specifications.
Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Apply the four universal firearms safety rules before loading or handling any firearm: treat every gun as loaded, never point at anything you are not willing to destroy, keep your finger off the trigger until ready to fire, and be certain of your target and what lies beyond it.
- Verify current federal, state, and local ammunition regulations in your jurisdiction — some municipalities restrict jacketed ammunition or impose additional storage requirements.
- This ammunition contains lead. California Proposition 65 requires notice that lead exposure can cause cancer and reproductive harm. Wash hands after handling and avoid inhaling particulate during reloading or range cleanup.
