Here are some pictures of a Woodleigh hydrostat that was recovered from my buffalo. The bullet (fired from 458 Lott) entered the skull just below the boss and contiued through the skull and entered the spine at the hump. The projectiles was recovered near the tail under the skin. The only damage to it was on the nose by way of very slight indentations.
