It's usually more than that. I got 186# of finished meat from the last cow elk I shot and it was about average size. A mature bull is much larger than a cow. Moose are so big they make elk look like antelope and the finished meat is way more than what you mentioned from a mature bull, as I've help on two in the last 10 years in Wyoming and Idaho. It can be taken home in a full size PU in some large coolers, but the truck will really be packed if you have a lot of other gear on the hunt to also take home.
