Sharp Shooter Supply Co. makes an extractor that you can fit (or have them fit) to the .473" bolt face to extract the 7.62 case, but sometimes it doesn't eject correctly, and they do state that on the website. They also will take a .223 bolt head, open it up, and fit the extractor to it, and then the cases will eject. Last time I looked, I think that it was $75 or so to get the new bolt head, and it was $30 to have the extractor fitted to the .473" (30-06 size) bolt head.
