I've watched the shows, and heard all of the aurguments...but seeing a 350 lb mountain lion rolled completely over 2 times when it was shot with a Ruger Blackhawk in .45LC from about 15 yeards was all I needed to see. And that was BEFORE the reaction to the pain...that was just the cat knocked over...
THEN it wanted to fight. Another shot, this one to the head, took that option away...
A big piece of lead that flattens out into a BIGGER piece of lead tends to make things stop, sit up and take notice before they get the second hit, or bleed out from the first.
I dunno know, but that would probably be the world record for a Mountain Lion, usually weigh 80 to 150 lb depending upon gender. Maybe a Tall Texas Tale. LOL.
