I believe wvhitman has used em alot in the 475 to good effect. I wonder how fast the hunter ran em on that eland rey? I know ya gotta run em hard on the big stuff. When i helped some friends guiding/recovering oryx in their ranch for a few years they were my go to stoppers for the oryx cuz they did so much damage. Theyd never pass all the way thru on anything other than totally broadside shots and typically would get caught in the hide and i suspect that had to do with the larger expanded diameter not escaping the hide. Never cared cuz the damage they do.
