Son shot his first buck(a spike) with one out of a 7-08. Perfect shot placement although the deer was quartering slightly. Deer tucked tail and ran. Waited on land owner to come help track. Got to shot site and zero sign. Looked where we thought he would have went and nothing. Finally I walked down a little cleared path in some pines and found him no further than 50 yards from hit site. When we cleaned him, the cup and core had separated and was lodged just under skin on opposite side. From then on I decided I would rather have an exit hole than to “expend” all energy of bullet in animal. Switched to barnes and haven’t lost one yet
