A method for processing explosives containing a high loading of CL-20 may advantageously include a binder system having naphthenic oil and/or paraffinic oil. Solid energetic ingredients are added into the binder system and mixed to form a free-flowing suspension in which the solid energetic ingredients are homogeneously mixed and coated with the binder system. The binder system is then cured and cast to form a cross-linked explosive.
