You pretty much lost me on the "I've never shot an elk", but if it hadn't been for that part you'd of lost me for sure on the later part..

Intresting comments.
Elk is a deer just like all the other deer species of the world it's the size of the animal, projectile and caliber relationship that counts. An 150gr ttsx won't do [bleep] all at 600yd unless hit in the head or neck. You will wound the animal and it will run away to die a miserable death.
Love to see any pics of an elk being hit with that projy and wouldn't it be nice to see the autopsy of said Elk as well, some real study of bullet performance, but hey if your google search skills are any good you may just come across something.
