Have someone knowledgable check the headspace, and have a borescope inspection of the throat. If those two items are okay, the rifle is good to go. The rest of the action is as close to bulletproof as you can get.
If the throat erosion is very bad, or the headspace is off, it could be rebarreled for a new lease on life.
