I haven't shot an elk with it, but a ~450lbs black bear was very impressed with the 100gr TSX at ~3300fps. Full penetration and exit holes, and the animal dropped at the shot each time. First shot spined him in the middle of the back as he was climbing up and away from me, 2nd shot was in the neck (no spine), and the 3rd shot was a frontal shot that entered the base of the neck and exited by the tail. Internal damage was significant.
