Abstract
A method of marking bullets and bullets marked by the method are described. In one embodiment, the method comprises coating the bullet of a cartridge with at least one coating material whose surface appearance contrasts with the surface appearance of the underlying bullet material. Characters are then selectively etched in, and generally substantially through, the coating, such as molybdenum disulfide. The characters are easily and quickly recognized because of the contrast between the surface appearances of the coating and that of the underlying material. The characters typically, but not necessarily, indicate characteristics of the bullet, such as bullet weight and design features.
