booped this one on the noggin with JSB 8.44s from my hw50s with the open sights at about 12-15 yards. Not a bad shot for open sights. Did a few flops and expired. The way it fell I couldnt see head and wasnt sure so I put a second shot into the body just in case, I was surprised to see it had gone through the back and exited out the front, very surprised to see a body pass through with a 12ft/lb 177
