Remington 257 Roberts 117gr Core-Lokt Soft Point Ammo - 20 Rounds

The Remington 257 Roberts 117-grain Core-Lokt delivers exceptional terminal performance for medium game hunting with its proven soft point design. This classic cartridge combines flat trajectory with controlled expansion, making it ideal for deer, antelope, and similar-sized game at extended ranges.

What Makes This Different

Remington's Core-Lokt technology mechanically locks the lead core to the jacket, preventing separation during expansion for maximum weight retention. Unlike standard soft point bullets that may fragment, the Core-Lokt maintains structural integrity through bone and tissue. This design has accounted for more big game kills than any other expanding bullet, with over 80 years of proven field performance.
