.348 Win.

The .348 Winchester is a rifle cartridge developed by Winchester in 1936. It was designed as a high-powered, big-game hunting cartridge that could take down large game animals like elk and moose.

The cartridge is based on a modified .50-110 Winchester case, which was necked down to accept .348 caliber bullets. The resulting cartridge has a bullet diameter of .348 inches and a case length of 2.015 inches.

The .348 Winchester is capable of firing bullets weighing between 200 and 250 grains at muzzle velocities ranging from 2,350 to 2,625 feet per second. It is a powerful cartridge that is suitable for hunting a wide range of game animals, including elk, moose, and brown bear.

The .348 Winchester was popular among hunters and shooters during the mid-20th century, and a number of firearms manufacturers produced rifles that were chambered for the cartridge. However, it has since declined in popularity and is no longer produced by Winchester or other major ammunition manufacturers.

Today, the .348 Winchester is primarily used by collectors and enthusiasts of vintage firearms. It is also occasionally used for hunting and target shooting, but ammunition can be difficult to find and expensive compared to more common cartridges.
