I wouldn't call this cool...maybe crazy. I shot a doe years ago with a .30-.30. She was across a deep ravine from me. I dropped her with the shot, and she rolled all the way down into the bottom of the ravine...at least a 70 yard roll to the bottom. She came to rest on her back with all four legs in the air. I'm still in my climber 8-10 minutes later, and I hear some noise down in the ravine where the doe had "died". When I turned my head and looked, that doe had stood back up and ran straight back up the hill out of the ravine and disappeared. I got down and walked over to where she had been lying "dead". No blood, no blood going back up the hill where she ran away. I walked up and looked all over that area. I never found her.
