Have this Mosin that has had a bit of th sticky bolt problem in the past. I know we don't want to resurect old threads but I'm getting ready to go to the range in a couple of days and was cleaning and lubing, is there anything that will cut invisible cosomoline ie (baked in/on) I hve tried the usual suspects and ain't thrilled about hosing my Mosin down with brake cleaner. I also noticed that and at the end of my bolts lift, (currently cleaned and oiled) that the bolt seems to drag about the last quarter inch. Is this related to my sticky bolt problem or some other problem of which I am unaware. I don't seem to notice that amount of drag on my M44 nor does it have the sticky bolt problem it has a slick bolt.
