Mule Deer, I think I used the same bullet that you used in the Roberts on a Virginia whitetail, with similar performance. I shot the animal twice through the lungs, and the wound channel from those never got larger in diameter than a nickel, the deer ran about 40 yards, where it stopped and looked at me. The third shot impacted below the right eye and exited the back of the skull through a hole the size of a pencil. There was no blood on the ground between the site of the first shot and the last. I stopped using that bullet. Changed to the 100 gr. Sierra, and the next deer I shot spun and fell with similar shot placement. I don't think it's rear hooves moved more than 6".
