I really don't care one way or the other but can present some info. on the weight tapes. If they have been standarized to the animal they are very close to actual weights. It is a common method of estimating a weight on a horse to figure drug dosages. I'm not sure if there is a standard for deer, if there is then the tape would be very close. The fact that it bloated would not affect the tape estimate. The GI tract is where all of the early bloating occurs, rumen and small intestine being the worst. These would have been removed during field dressing and wouldn't affect the circumference of the chest.
