Remington Core-Lokt 7x57mm Mauser 140gr PSP Hunting Ammo - 20rd

The Remington Core-Lokt 7x57mm Mauser delivers proven expansion and deep penetration for medium to large game hunting. This 140-grain pointed soft point ammunition has accounted for more big game harvests than any other expanding bullet design, making it the standard by which hunting ammunition is measured.

What Makes This Different

The Core-Lokt design mechanically locks the lead core to the copper jacket, preventing core-jacket separation during expansion. While standard soft point bullets can fragment or fail to expand consistently, Core-Lokt maintains 95% weight retention through controlled expansion. The pointed profile delivers flatter trajectory and higher retained velocity compared to round nose designs in the classic 7x57mm Mauser chambering.

Key Features

• 140-grain pointed soft point bullet optimized for medium game hunting
• Mechanically locked lead core prevents jacket separation on impact
• 95% weight retention ensures deep penetration and reliable expansion
• Pointed profile reduces wind drift and extends effective range
• Premium brass cases with consistent powder charges for accuracy
• Boxer-primed cases suitable for reloading applications
• Factory-loaded to SAAMI specifications for reliable function

Field performance demonstrates consistent 2-3x diameter expansion across various impact velocities. The 140-grain weight provides optimal sectional density for the 7x57mm cartridge, balancing flat trajectory with sufficient momentum for ethical kills on deer, elk, and similar-sized game. Muzzle velocity reaches approximately 2,660 fps from 24-inch barrels, maintaining over 1,800 fps at 300 yards for reliable expansion.
