I used 140 Amax in 6.5x284 Killed a number of deer both Whitetail and Mule all shots at under 300 yards. I only found peace of bullets, and have had at least Two backbone shots where the bullet traveled a good distance in the spinal collum I switch to a 140 Nosler that shot the same group It's a bone crusher and holds together. I would not use Amax on Elk they are a much tougher animal I learn a painful lesson along time ago in Montana. Tracked a wounded Elk over 10 miles shot with a 270 and the bullet came apart A third of the meat was soured and jellied.
I wouldn't use it on elk, just coues. I have other bullets set aside for Mulies and Elk. Thanks for the input
