Never forget to remove the bore sighting device prior to shooting, or this could happen to you. Luckily for this sharp shooter, the accident happened at the firing range where there were people around to react quickly and rush for help. Had this sportsmans taken one of his used snowmobiles to the middle of the woods and then had this happen, he would have been in a lot of trouble, since their would have been no one there to call for help and rescue him.
