Was waiting to shoot tonight. Watching a squad shoot. On about the sixth shot one of the shooters called pull and his shotgun went phuft. He looked around and then removed the empty. I saw that no wad went down range. One of the other guys said I think you had better check the barrel. Sure enough the wad was in the barrel. I took the fibreglass stick out to him. This happened four more times in the next eight shots. One of the other shooters went and got him a box of factory shells from his truck. He still had eleven shells in the box. he said when they were done I think I forgot to put powder in them. He then said I wonder how many are in the other boxes? All five I watched were primer only.
