Cartridge Size Optical Measuring Instrument

technical field

The utility model relates to a measuring device, in particular to an optical measuring instrument for the size of a cartridge case.

Background technique

Bullets are the most widely used, most consumed, and fastest produced among all kinds of weapons and ammunition.
