For hunters working medium to large game at extended ranges, 280 Remington ammo with a polymer tip delivers the flat trajectory and terminal expansion you need when the shot window closes fast. The Remington Core-Lokt Tipped marries the proven jacket design of the original Core-Lokt with a polymer tip that improves ballistic coefficient and initiates rapid expansion on impact. At 3020 fps from the muzzle, this 140 grain load carries 2835 foot-pounds of energy downrange — enough authority for elk, black bear, mule deer, and whitetail from 50 to 400 yards. Each round is loaded in reloadable brass with a non-corrosive Boxer primer. Remington has been loading the 280 Remington cartridge since its introduction in 1957, and the Core-Lokt Tipped variant represents the current evolution of that engineering.
Load Profile
The 140 grain polymer tip bullet in this load achieves a G1 ballistic coefficient of 0.486 — a meaningful improvement over traditional soft points in the same weight class. The tip moves the center of gravity rearward, stabilizing flight and flattening trajectory. At typical hunting distances, you gain 2-4 inches less drop at 300 yards compared to a flat-base soft point, which translates to a wider margin for error on hold-over and wind drift. The Core-Lokt jacket is engineered to retain 75-85% of original weight on impact, shedding the front core in controlled petals while the bonded rear drives penetration. This is a proven big game design — thousands of rounds in development, field-tested across North American species.

Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle 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.
- Always observe the four fundamental rules of firearms safety — treat every firearm as if it is loaded, never point the muzzle 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 that your rifle is chambered for 280 Remington before loading this ammunition. Do not use 280 Remington ammunition in firearms chambered for 7mm-08 Remington, 7mm Remington Magnum, or other 7mm cartridges.
- This ammunition contains lead. Wash hands thoroughly after handling. California Proposition 65 warning: this product can expose you to lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information visit www.P65Warnings.ca.gov.
