An elk's hide is amazingly stretchy and tough. Even with a 300 WSM and premium bullets, I've had them stopped by the hide on the far side. They do an exit from the body but the hide will stretch way out and stop it. That has no affect on killing power since the bullet has completely penetrated. It just doesn't poke another hole.
