Some 99 stocks crack due to the wood checking as it ages. My 99EG had the Savage crack, so I fixed it and glass bedded the four places the stock and action meet. The buttplate on my gun (a pre-WWII piece) is about 1/16" larger than the wood now that the gun is 77 years old and has shrunk. A friend's 99F made around 1970 needed major stock repair. The "fingers" which fit inside the action on the sides were so flimsy that they broke off. I had to make new ones and epoxy them on.
