I don’t know what brand bullet he was using but I tracked a big buck for a guy last year that had been shot in the point of the shoulder with a ballistic tip out of 300 mag. He said the deer dropped down on his front side leg nearly to the ground and then spun around and took off. It apparently just exploded on its shoulder and didn’t penetrate well. We tracked it 14 hrs after the shot and jumped it up still alive about 300 yards from the hit site.
