ABSTRACT OF THE DISCLOSURE A deformable molded fiber product is formed by a method of felting, pressing and drying the compressed product having a uniformly spaced series of low density ridges on one surface. These ridges provide the molded fiber product with sufficient flexibility so that it may be subjected to a hot swaging like process to change its dimensions. A method of forming detents by hot pressing is also shown. The process is particularly useful in forming combustible nitrocellulose shell casings from a single pulp molding operation.
