I've not taken an elk but have taken a rather large red deer stag in Europe. That was also taken with the same 270 hand load. Not any real difference that I could tell. But the way I checked out the Triple U Ranch website and they recommend anything from 270 up. Triple U is in South Dakota just north of Pierre and is where the movie Dances With Wolves was filmed. I hunted my bison there back in the mid-90's. Really good folks there. At the time I hunted there they had the largest bison heard in the world. Ted Turner's herd is now larger.
