I'll bet the guy didn't know what he had done, he loaded 3 in the magazine 1 in the tube fired his rounds thought good enough and went home leaving the evidence behind, over the years I've witnessed a 223 being fired in a 220 swift took the guy a number attempts to get the thing to go bang, I'd have bet money you couldn't get the thing to fire, that guy earned himself a trip to the ER, 270 in a 280, 280 in a 06, 300 savage in a 308 Winchester, 338 federal in a 338 Winchester, 338 Winchester in a 7MM STW and another earned trip to the ER,
