I've weighed a pile of cows and young bulls boned out. Never had one break 200. Had an outfitter tell me the biggest bull they ever killed had 89lb hind quarters bone in. Most think they all weigh1k on the hoof.
I participated in the elk reduction effort in Teddy Roosevelt Nat'l Park in 2011. They took all cow elk that year and If I'm remembering correctly, the largest rear quarter was 71# bone-in off of a giant old grand-mammy.
