Remington’s Core-Lokt Copper brings the company’s century-old Core-Lokt reputation into the lead-free hunting era. This 300 AAC Blackout ammo loads a 120-grain solid copper hollow point to 2100 fps from a 16-inch barrel, delivering 1175 ft-lbs at the muzzle—enough terminal energy for whitetail, hogs, and predators out to 200 yards while satisfying lead-free mandates on public lands and in California. The monometal bullet sheds no lead fragments, retains 95%+ of its weight through bone and tissue, and expands reliably across subsonic-to-supersonic velocities. Remington loads each round with a lead-free primer and Boxer-primed brass cases, maintaining the clean-burning reliability hunters expect from the Core-Lokt line.
Load Profile
The 120-grain solid hollow point uses high-strength pure copper—no bonded cores, no lead alloy—to achieve controlled expansion without fragmentation. Remington engineers the hollow point cavity to open at 1800 fps and above, peeling back into a four-petal mushroom that doubles frontal diameter while retaining nearly all its mass. At 2100 fps, energy stays above 800 ft-lbs past 150 yards—sufficient for ethical medium-game harvests when paired with proper shot placement. The G1 ballistic coefficient of 0.251 reflects the solid-copper construction; expect 8-10 inches of drop at 200 yards with a 100-yard zero. Boxer primers and reloadable brass let you reclaim your empties for handloading once factory stock runs low.

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.
- Observe the four fundamental rules of firearm safety on every range session.
- Verify your state and local laws permit purchase and possession of ammunition before ordering.
- Confirm your rifle’s chamber and barrel are rated for supersonic 300 Blackout; never load 300 Blackout into a 5.56 NATO chamber.
