Does the meat weight include bones? Also, did they add any fat to make sausage or ground meat?

I wish I could remember the formula I saw once. It gave live, dressed and boneless meat weights. The 40% thing sticks in my mind though. Live weight x 40% equals boneless weight. If that is indeed correct, your deer weighed 350 on the hoof.

I'm not saying one way or the other, and that deer is real nice, but I don't think he'd go 350 live.
