8×125

8×125 refers to a specific ammunition designation. The "8" indicates the caliber, which is 8 millimeters. The "125" refers to the case length in millimeters, meaning the cartridge case measures 125 millimeters. This designation is used for a type of rimless rifle or machine gun ammunition.

Ammunition designated as 8×125 would typically be a centerfire cartridge. The "rimless" aspect means the cartridge case lacks a prominent rim, which is advantageous for reliable feeding in automatic firearms. The case head is often designed with an extractor groove to allow the bolt to grip and extract the spent casing.

While specific firearms chambered for 8×125 ammunition might exist, it is not as common as many other military or sporting calibers. Its usage would likely be tied to particular historical firearms or specialized applications. Without further context, it's difficult to pinpoint its exact origins or widespread adoption. However, understanding the "caliber × case length" format allows for the basic identification of its physical dimensions and general type of ammunition. This naming convention is standard in firearms and ammunition terminology, providing a clear way to distinguish cartridges.
