7×203
7×203 refers to a specific type of artillery shell. The "7" indicates the caliber of the weapon, which is 7 inches. The "203" denotes the length of the shell in millimeters. Therefore, 7×203 is a 7-inch artillery shell measuring 203 millimeters in length. This designation is a standard format used in some countries to classify artillery ammunition, providing key dimensions for compatibility and performance. Such shells are designed to be fired from howitzers or cannons of the corresponding caliber. The specific type of propellant, bursting charge, and fuse would vary depending on the intended use of the shell, such as high-explosive, illumination, or smoke. While the caliber is significant, the shell's overall effectiveness and range are also determined by the weapon system it is fired from and the ballistic properties of the projectile. Further specifications would be found in detailed military ordnance catalogs and technical manuals.
