It took me a minute to figure out why you would process it that way then it came to me, lol. You don't see "train kill" deer very often I imagine. To date the largest buck I had hanging in the butcher shop with no skin, hooves and trimmed of fat was 202lbs. It was a big beast with a decent 165" rack; but most bucks I've hung are around 150-160#'s normally.
We have mandatory CWD testing in this area too but I don't hear of many people bringing in their heads I'm afraid.
