The Below Information Has Been Provided From Our Gun Caliber Dictionary And Is Meant For Informational Purposes Only. It Is Not Intended to Describe The Unique Specifications For This Ammunition.
The 257 Roberts was wildcatted by gunwriter Ned Roberts in the 1920s and introduced by Remington as a factory cartridge in 1934. Based on the 7x57 Mauser cartridge necked down to take a .257-inch bullet, it was probably the first cartridge viewed as a combination varmint and big-game cartridge, the role the 243 Winchester stars in today. Mild in recoil, accurate, flat-shooting, and extremely effective on game, the 257 Roberts is rarely seen in new rifles today but retains a substantial and extremely loyal following. Standard velocity is a 117-grain load at 2780 feet per second, but a standardized "+P" 117-grain load at a very speedy 2940 fps has been available for many years. Many of its dedicated fans use it for elk, but without question it is best-suited for pronghorn and deer-sized game. —
