Feels a light. I would have thought it would yield +50-60 pounds as a rule of thumb.
I switched to processing my own after seeing how my butcher was handling things. Not really an issue of cleanliness or anything, but just a strong suspicion that he was comingling certain aspect of the process like grinding and then just portioning it out etc.
I shot a big doe last year that weighed close to150, processed it myself, took all the meat off neck, ribs, etc. and it was over 60 pounds with no additions.
If you have the time and desire, I would recommend giving it a try. After a bit of trial and error, I have a kit with about $100 in gear (knives, cutting boards, wraps, folding table, etc.) plus a $70 LEM grinder that fits into a tote in my truck. I can process 1 or 2 deer in the field, if I want, or do it back home after they hang a bit. I can even do the grinding right there with an invertor or access to an outlet, although I usually do that at home.
Doing it yourself also let's you play with organ preparations, caul fat, neck roasts, braising shanks, etc.
