- The .358 Winchester is a rifle cartridge that was introduced in 1955 by Winchester. It is based on the .308 Winchester cartridge and uses a necked-up case to accept .358-inch diameter bullets.
The .358 Winchester cartridge is designed for use in lever-action and bolt-action rifles, and it is commonly used for hunting medium to large game such as deer and elk. It offers excellent accuracy and stopping power, making it a popular choice among hunters who prefer a heavier bullet with a larger diameter than more common cartridges such as the .30-06 Springfield or .308 Winchester.
While the .358 Winchester cartridge is not as widely used as some other rifle cartridges, it has a dedicated following among hunters and enthusiasts who appreciate its excellent ballistics and stopping power. It can be more difficult to find ammunition and firearms chambered for this cartridge, but it is still manufactured by Winchester and other ammunition companies.
