.35 Win.

The .35 Winchester, also known as the .35 WSL (Winchester Self-Loading), is a rifle cartridge developed by Winchester in 1905. It was designed as a medium-power cartridge that could be used for hunting medium-sized game at short to medium ranges.

The cartridge is based on a modified .351 Winchester Self-Loading case, which was necked up to accept .358 caliber bullets. The resulting cartridge has a bullet diameter of .358 inches and a case length of 1.71 inches.

The .35 Winchester is capable of firing bullets weighing between 150 and 200 grains at muzzle velocities ranging from 1,800 to 2,000 feet per second. It is a relatively mild cartridge that is suitable for hunting a wide range of game animals, including deer, black bear, and wild boar.

One of the main advantages of the .35 Winchester is its suitability for use in self-loading rifles, which were popular during the early 20th century. The cartridge was originally developed for use in Winchester's Model 1905 and Model 1907 self-loading rifles, which were popular among hunters and shooters at the time.

However, the popularity of self-loading rifles declined in the mid-20th century, and the .35 Winchester cartridge fell out of favor. Today, it is primarily used by collectors and enthusiasts of vintage firearms.
