I've never weighed one either.....
I do know that when I drew a tag, the Alaska F&G sent me a letter stating that the Roosevelt bulls on Afognak and Raspberry Islands can weigh in excess of 1200-1300 pounds. I thought: "no way". I've killed lots of elk and even though Roosevelts are bigger, there's no way an elk can be that big.
Well when I got over to my bull, I scratched my head and said $hit.....I'll bet this thing weighs 1200-1300 pounds....
Each boned out quarter was substantially heavier than the bone in quarters of the Rocky Mountain raghorn I killed a couple weeks ago.
Further north one goes,the elk run bigger. Elk shot say in Alberta are bigger/heavier than the elk shot in Colorado,although they are both descended from Yellowstone elk.
Look at bears. The largest , Brown and Polar are far north.
