Hi skeeter 7MM,
If this is something you'd like to try on your own...check this Brownell's site:
http://www.brownells.com/aspx/NS/Store/Search.aspx
Once you get to the search site look under Birchwood Casey (refinish blueing).
If it is something you don't mind spending a little money on there are finishes other than blueing that have some major advantages. Black Teflon finish for instance is water proof/resistant and does not need lubrication. It is self lubricating. Only disadvantage is that the process cost about $200. or just a little more! Worth the money on a nice rifle that will be used in wet climates!
Good luck with your search!
