I have seen a few failures with .243 and .25 caliber rifles on elk, but not to say they won't kill an elk. Anything less than a stout 7mm is off the menu for me on an elk hunt. All the anecdotal evidence presented won't make a 6mm an ideal elk caliber, but use whatever lets you sleep at night. Happy Trails
