RE: Is it necessary and what is/are the advantage(s)?
walks:
First, your use of firearm calibers and gauges is not a realistic comparison. And the coal comparison is a great one. However, if you want to go that route; would you recommend using a 3" magnum No. 4, 12 gauge with a turkey choke to shoot pheasants?
Second, I thought we were past the discussion of an inappropriate act. However, since you reintroduced some of the thread by saying,
"I think you're making way too much of a new product being tested in the field under average conditions by a talented hunter with lots of in the field experience that knew the outcome of the shot before it even happened...."
I have no choice but to reply. Bull! I have been in the sport long enough to know that talent and field experience does not guarantee anything. Why? Because the game animal and Mr. Murphy have a say in the matter.
Q: If one already knows what the outcome will be, why perform a test on a live animal? [:@]
