Couple years ago my brother in law shot a moose cow….didn't see the calf a good ways behind it. Did you know that the boring old 180 grain Winchester power point out of a .308 can kill two moose with one shot!? Double lunged the cow, meat saver shot, exited and hit the calf also by luck (or bad luck) right in the chest as well. Both animals were stone dead by the time he got there. He felt sick! Absolutely terrible. But lucky for him I had also been drawn for moose that year. I'll admit I was pretty choked that I didn't go moose hunting that year BUT also noted that the other two times I've been drawn I struck out. Put my tags on the calf, no harm no foul. And if you've never had calf moose…well holy smokes it makes beef seem like leather haha. Not the worst thing in the world to have one's brother in law owe you a favour haha, took him up on it installing some flooring a while back
Point is, these things do happen.
