Gun + scope was probably dropped or bumped, and scope got knocked off kilter. Been there done that, After a buffalo hunt, thank God. The guide put my marlin 45-70 in his truck, then opened the passenger side door of his truck for me...the rifle fell out of the passenger side of the truck. Either he was really stupid, or he didn't like girls who did one shot kills on buffalo with 45-70's. I tipped him anyways. Yeah the scope was junk after that.
