Yep. I learned that the hard way. It's no fun killing them by strangulation.
My father in law shot one back 15 years ago or so and loaded it in the truck. When he was driving out he had to stop to unlock the gate and when he did he heard something and looked back towards the truck and the buck was standing up in bed of the truck. My FIL jumped into the back and grabbed the deer by the antlers and somehow was able to jam them under the toolbox. Deer was sluggish but still very much alive. His gun was on seat of the truck and his knife was in his jacket pocket on the front seat. He managed to get the tool box open and found a ratchet strap and got it around the deers head. Twisted it until he thought it was dead and then let off, only to have the deer "wake up" again. He got the strap back around his neck and used an open end wrench to twist it until he heard the neck pop.
I drove up to him while he was still sitting there trying to catch his breath. Dont know how he didnt have a heart attack.
