OK maybe I shouldn't bring up the weight topic again

but here's the deal. I took the four legs from my cow elk to hang in the meat locker with the lower legs removed. he said they weighed 245 pounds. So if you add the lower legs, backbone and backstrap, ribs, neck, head, hide and guts, Then how much did this old gal wiegh on the hoof. I couldn't find a good formula on line that was based on the legs only. Anyone have one?
