The .358 Winchester is a .35 caliber rifle cartridge based on a necked up to .308 Winchester created by Winchester in 1955. The round is also known in Europe as the 9.1x51mm.
.358 Winchester, including Chuck Hawks' article on the Rifle Cartridge Page of Guns and Shooting Online, based on what I have read, everyone who has used the cartridge has had nothing but high praise for it.
This cartridge came over 30 years later than the .35 Whelen, which is based on the .30-06 Springfield. The relationship in performance between the .358 Win and the .35 Whelen is similar to that between the .308 Win and .30-06.
