I don't know about elk but I knocked the absolute dogchit our of a black bear (500+ lbs weighed/dressed) about a decade ago with a 160 gr speer mag tip. I don't even know if they make the bullet anymore. It was a tack driver with W760 and for under 300 yards it would work as good as anything. One of those rifles I should have never sold but a good kid needed a good deer rifle so there it went.
