Welcome to the party. This has been discussed a few times. Until someone brings Adamantium to the market the 9310 steel is about as stron as you're going to get for a bolt.
At 65ksi you're talking magnum pressures, I think you meant the 60ksi that the 5.56 and 308 are pushed to.
Even if you can get a bolt that can handle that pressure, you're limited by the mag length of the AR15. To fit enough powder in the Grendel case you'll need to load to a longer COL than 2.3".
The Grendel needs a new platform to maximize it's potential. However, the gains you'll achieve don't really make it worth the investment of a new platform. That being said, the new DTA bullpup seems like it was designed for the Grendel.
