Not 162 ELD-X but 200 ELD-X out of his 300 WM. My hunting buddy shot a very nice bull elk and almost lost it. He put 2 rounds through the lungs at 400Y+. The bull managed to run back into the timber over a 1000Y; that is correct. Four of us looked for over an hour to no avail. Another hunter above us was watching and nice enough to tell us where the bull had expired. There was a spec of blood 5Y yards where he passed. We found 2 tiny holes in the lungs without a pass-through, and the bullet did not expand. He also shot a muley buck at 200Y and was able to run 400Y; the same result as his elk, no expansion.
He was using factory ammo. He sent the remaining box to Hornady, and they did not find anything wrong with them. My buddy stopped using them. I have over 300 .30 cal ELD-X that I hesitate to use on a game after his experience. The bottom line is that we all have varying experiences and need to know which is best suited for our intended purpose. Some people here and elsewhere have a better experience with the M over the X.
Good luck!
