ABSTRACT

Also present in ammunition is a range of lubricants (greases and waxes) usually confined to unjacketed bullets, as well as various sealers, varnishes, and lacquers (often colored) that are used for several purposes. These include prevention of the ingress of moisture or oil, anticorrosion measures, to act as a visual aid in the manufacturing process, to provide additional resistance of the bullet to the pressure generated by the propellant gases, and color coding to identify the type of ammunition. The bullet tip may also be color-coded to identify the bullet type. A variety of sealing discs may also be present in different types of primers, some of which contain tin.
