Watched my partner hit a chuck with a matchking out of a 300 Ultra mag. I continue to invite him along if only to see the results - sad thing is he never gets to see the impact and I'm not willing to shoot the Ultra. There were three of us and the two spotters agreed on the 6 foot vertical estimate but differed on the number of flat spins, somewhere near 2 complete spins with parts flinging. The shot was a tad low but the chuck was lying on an angled flat rock.
