I inherited a Savage Model 25 Octagon barrel 22 pump action rifle that is in need of a good cleaning and lubrication. Anyone have or know of good videos on breaking it down for cleaning, how the mechanism works, diagrams, schematics, drawings, photographs or other information to guide me in disassembly, cleaning, reassembly? How about a gunsmith or other individual who is an expert on this rifle or an knowledgeable owner?
