The .375 Winchester is a modernized version of the .38-55 Winchester, a black powder cartridge from the 1880s. .375 Winchester was introduced in 1978 along with the Winchester Model 94 “Big Bore” lever action rifle.

Though very similar in appearance to the older .38-55, .375 Winchester operates at much higher pressures (50,000 cup) (also the case of the .38-55 is slightly longer and its bullet diameter .3775 is larger than the .375 Winchester)
