The 257 Roberts original began as a wildcat cartridge which was designed by N.H. Roberts (a well known firearm
writer at the time). It was produced by necking down the 7x57 Mauser (.284" Cal.) cartridge to 257" caliber.
For many years the 257 Roberts was referred to as the most useful (all around) rifle cartridge, for
use on varmint, antelope, black bear, deer, sheep and goat.
Under loaded by most ammunition companies for many years, it is now available in the more
powerful +P loads in velocities up to 3850 feet per second and energy up to 2,134 foot pounds
per square inch.It was quickly picked up by Winchester and Remington, who produced rifles and
ammunition commercially for the general public.
Remington even
(incorrectly) named it the 257 Remington for a short time.
