I am simply stating that "looking at the operator" is not a fair statement.
If that was the point you were trying to make, why make the snarky comment about bowing to me?
The question was not about marksmanship, or canyons, or anything else. It was whether or not the 270 WSM loaded with 140 grain Accubonds was sufficient to kill elk. I will firmly stand behind my comment, more specifically that the operator either 1) took a shitty shot they shouldn't have or 2) did not make a "good" shot regardless of what they would tell you.
Shock doesn't kill. Loss of blood volume and CNS incapacitation are what kill (or long term infection for a poor shot). Not all double lung shots are created equal. A good shot to the center of the circulatory system equals a dead elk in very short order.
If you can shoot a big gun well and want to, have at it.
