Yeah, it was bloody--and all the petals were gone, which I've seen happen a few times before when various petal-type bullets hit bone, including the Original X and Fail Safe. The stump retained 62% of the bullet's original weight, but I found one of the petals a couple inches away from the bullet.
There was obviously no need to shoot the elk again. It wobbled about 25 yards and keeled over.
