I run grease on the high load areas. Locking piece and rollers.I keep reading here and there about GREASE as part of the lubing of these rifles. If this is the case, what parts are to be greased. I only put a very light dose of oil on parts that move against other parts when I lube all my other guns. Like the bootom of the bolt where it engages the hammer and the lugs and grooves of the action etc.
