Don't know what went wrong but a couple of years ago I walked into a local gun shop and there on the counter were the pieces of a new Browning A bolt in .25-06 seems the guy that was shooting it getting ready for deer season in a hurry of course was shooting several different rifles and calibers one happened to be a .308 by mistake chambered a .308 in the .25-06 and it went off. No one got hurt but the rifle was a total wreck, barrel split in half from the receiver forward most of that gone, the bolt was laying in the bottom half of the action it apparently never moved the rear part of the receiver was intact, scope gone was a new Leupold 4X14 the guy shooting had a permanent indent on the top of his nose and a permanent flinch I would guess. All said and done I would say very lucky, there were several other people around and no one was injured in any way. Can't be too carefull.
