Can certainly see how a bullet would bounce off a beaver's skull if it was looking at you. Darn flat and thanks for the photo. Took a second to realize what I was looking at. "Klingons?" sez me noodle for a second...
I am VERY tempted to take that skull out back and load up my old 3 screw single six with CB Longs and.........see what happens at 10 feet (shooting down between the peepers). But since I already know what the outcome would be (a destroyed beaver skull), I am not going to do it.
