Abstract
The present invention relates to a method of applying a wear protection substance to the inside of metal cases used for ammunition. The wear protection substance comprises a composition of wax and a solid particle component which has a known barrel wear reducing effect. The wear protection substance is either applied in molten form to the inside of the metal case or is applied in solid form to the inside of the metal case and then melted. The wear protection substance is then spread to form a layer over the inside of the metal case. The metal case is then cooled whereby a solid coating is formed on the insides of the metal case.
