This might be a little hard to explain. The inner part of the bolt came off the outer part... Does that make sense?
You could hold the bolt handle in one hand and the firing pin, safety, spring assembly, etc. in the other. If you know the Carcano bolt (and I didn't until this afternoon) I think the little notch that holds the safety in the bolt assembly made its way out somehow. They were shooting S&B commercial 8mm and when he worked the bolt the middle section of it fell out. I definitely don't want to put my head behind that bolt and pull the trigger again.
