Remington Core-Lokt 280 Remington 140 Grain PSP Ammunition - 20 Rounds

The Remington Core-Lokt 280 Remington 140 grain PSP ammunition is purpose-built for serious hunters who demand proven, reliable performance in the field. This is the load that has earned its reputation through decades of consistent, ethical kills on big game across North America and beyond. If you're running a .280 Rem rifle and want ammunition that delivers predictable results when it counts most, Core-Lokt remains the standard against which other hunting loads are measured.

What makes Core-Lokt stand out is its controlled expansion design. The tapered copper jacket is mechanically locked to a solid lead core, engineered to expand reliably while retaining weight through the animal—translating to deeper penetration and more effective energy transfer. The 140-grain bullet weight in .280 Remington splits the difference between lighter, faster rounds and heavier, slower ones, making it a versatile choice for medium to large game at typical hunting distances.

You get 20 rounds per box, loaded to a muzzle velocity of 3000 feet per second. That velocity combined with the bullet's ballistic coefficient of 0.39 gives you a reasonably flat trajectory and decent velocity retention downrange—important factors when you're glassing a distant ridge or setting up for a longer shot. The pointed soft point configuration provides both aerodynamic efficiency and controlled expansion characteristics.

Core-Lokt ammunition isn't flashy or laden with marketing hype. It's simply the choice hunters have returned to, season after season, because it works. Whether you're hunting elk, deer, or other big game in varied terrain, this 280 Remington load gives you the foundation for a successful hunt.

How does Core-Lokt ammunition expand on game?

Core-Lokt bullets are designed for controlled expansion, with a tapered copper jacket locked to a solid lead core. This construction delivers expansion while retaining weight, which helps maintain energy transfer and penetration through the animal.

Is this ammunition suitable for long-range hunting?

At 3000 fps muzzle velocity with a ballistic coefficient of 0.39, this load provides decent downrange performance and velocity retention. It's effective at typical hunting distances, though trajectory and energy will diminish at extended ranges—success depends on your specific rifle, your shooting skill, and the actual distance.
