What are the Ethics of a 940 Yard Shot on a Whitetail

How far is too far? That really is a tough question.Everyone has a different skill level when it comes to shooting. Personally I am not confident hitting steel at that distance, but I know a few people ring the bell 99 times out of 100. But do those skills transfer to shooting an unpredictable animal?

Non-Typical Hunts posted a video on Facebook of a hunter shooting a deer at 940 Yards.

What are your thoughts on this? As stated in the video the bullet has a 1.5 second flight time. A lot can happen in that amount of time. The deer took a step in this video and they were lucky to get it. I do not doubt the shooters skill or his guns ability to make the shot. What I question is the unpredictable nature of a live target.

Nailing down what is too far is hard. First thing is the shooters ability should dictate what distance is too far, but is there a point where the shooters ability is greater then an ethical shot distance?
