Bulls can be from 700lbs on up to......well not sure what the heaviest has weight in at
Cows are usually 500lbs to about 700lbs.
These are numbers I've seen published. Hunted these things most of my life, but never actually had the capacity to weigh one in the field. Not sure how one would go about doing that. Only know generally how much meat they will yield once butchered.
Let me just say that these animals are too heavy for your friend to haul out of the mountains by himself. You need help with elk.
Elk like any game animal can vary widely in weight. From around 400-500 for cows up to 1200 lbs for a very large bull. I would say average weight for a full grown bull would be in the 700-800 range and for a full grown cow about 500. This is for Rocky Mountain Elk in Colorado. Don't know if elk in other states run larger or smaller.
The hind quarters on my bull this year were about 120 lbs. They say if an animal is butchered correctly you will yield about 50%-55% of the live body weight in meat. My bull this year yielded about 350 lbs of meat so I'm guessing he weighed about 700 lbs.
From what I've seen published is about what WesternHunter mentioned.
One time we weighed the guts of a bull moose(field dresed) and I believe it was either 125 or 135 lbs.. Animal was then 650 lbs. After skinning,head removed,legs etc, I believe we got about 350 lbs of good meat.
I 'm going to go with about 60- 65 % loss from the hoof to the dinner plate
I've spent countless hours either on my hands and knees or bent over, messing up my back, looking for blood. One such instance I remember most was a hog hunt a few years ago in Mississippi. I had never shot a hog so when I poked a hole in this guy; I was determined to find him. Wearing snake leggings, I crawled on my hands and knees through the briars and the brambles and bushes where a rabbit wouldn't go. I found a spot of blood here and there but never the pig. And lucky for me, I didn't find...
