I'm surprised that your dents won't steam out ! You did remove the old finish before you attempted to remove the dents ? If you don't take it down to bare wood the grain won't raise , which is what removes the dents ! You can also raise the grain at the buttplate and sand out some or all of the water staining , without removing much wood . If this is your first go at restoration , I'd advise practicing on some old junker stocks before you tackle your Winchester . Duplicating the stain is the tricky part . Brownells has one that's supposed to be a good match , but I haven't tried it so can't say either way . I'd be happy to provide what help I can , feel free to PM .
