When I was a hunting guide in Idaho and Montana, I packed a Ruger .243 and only did head shots. Usually it was a put down situation around a 100 yardsor so, where the dude made a bad shot and I finished it off. I have killed a few elk with that 243 lung shots using 120 gr bullets, but not more than 150 yards. You can shoot an elk in the ass with a 458 and it will run 10 miles or shoot an elk with a 22-250 in the head and drop it. All depends on shot placement.
