Yes, Rugers did have the problem in the mid-1970s. I have two of them - one a .243 Liberty 1B model, with fairly plain wood, and a .375 H&H, from 1977 which has really nice wood. The 375 I will try to save the wood on. Every few months I rinse it with distilled water, then let it dry. Eventually I will seal it, and see how it does.
