Regardless of whose story is true/more accurate, the reality is this:
They were both in the wrong, BUT-
It sounds like she is a relatively new hunter. Whether she chose to take a 630-yard shot or she was “mentored” to, she very likely shouldn’t have been shooting at all. That’s no distance for a novice to be shooting at anything but paper.
However, Mr. Von WhatsHisName is a self-proclaimed professional in the field. He admittedly took an un-ranged, 730-yard shot at a quartering-away deer, that he hadn’t even identified well enough to see whether it was collared.
Just tossing lead and a prayer.
If you cut it down to basics, both shooters were wrong. He was just MORE wrong.
Everything after that is a declining sh!t show where he appears to be the conductor.
Every hunter I know would have approached her, asked what happened, and then offered to go help her finish HER deer.
I had a very similar situation happen where I walked off the mountain without a buck that only had my bullets in him, so maybe I’m biased.
However, I can’t imagine any experienced, ethical “sportsman” essentially bum-rushing in and double-tapping someone else’s buck just so they can mark the mule deer box on their quest to “Kill All 5 North American Deer Species” in a season.
