I've been processing moose for a long time.
An average moose in this country weighs 900 to 1000 lbs on the hoof which results in somewhere between 300 to 400 lbs of boneless meat.
I have several freezers here (Box Type--hinged lid on top)5ft long maybe 2ft wide and 3ft deep. An average moose will fill one about 3/4 full, cut and wrapped.
That's what we find too. Expect about 35%-40% of the live weight in boneless meat.
That has been my experience as well.
I think my experience has shown me that you get a little less than a third of live weight for freezer ready meat, but I wouldn't argue with kkahmann. He deals with lots of animals.
Only thing I can say is the older I get, the heavier the dead moose feels at the kill site, and the less it weighs at freezer time.
