I had the same luck with a Ruger 77 Hawkeye they had listed in 358win. Excitedly I called to place my order only to find the 358win's were sold out. I order a Winchester 1886 in 45-70 from them years ago; great service and incredibly low price. I normally check their sight for their catalog updates, then purchase quickly if they have something I "can't live without". I'd bet you can find the stocks that came from CDNN on eBay....of course selling at twice the price.
Good luck in your search. As an alternative, have you looked at Boyd's Laminate Lightweight Varmint Thumbhole stock? It is very light...3.5# if I remember correctly. I bought one for my son's 30-06. Very nice stock and beautifully machined.
