I've told the story of my son's pre-64 ".30/06" here a time or two. The case from that episode ruptured, spraying his face with bits of powder, etc., blew the extractor off the bolt, and bent the floorplate. He worked at the store where he bought it and they took it back to send to their central gunsmithing center for analysis and repair.
He grabbed it when it first came into the store, so it was never test-fired into the snail they had. He did most of their test-firing so it would have likely gotten him anyway, except he would have been wearing a face shield and apron instead of just shooting glasses.
