There was a little old man I used to work with who hunted at Least 5 days a week during hunting season. He shot( maybe missed) & lost the biggest buck of his life and he had killed more big bucks that any one Im personally aquanted with. Makes him sick till this day. He instantly went and bought a 300 win mag and now shoots 220gr bullets. That was his reason. Would more practice shooting helped? Probably. But he was convinced he didn't miss. He went to the extreme in order to eliminate any chance of that happening to him again. It was all the reason he needed. To each his own.
