Bulzeye, I said it is an estimate not an actual. Even if you dropped 15 pounds of the guts your looking at 50 lbs of meat with 1/3 formula..it is the best way i know to guess at what you'll get out of an animal. Also your 130 include the hide, head and so on...drop that weight off and you'll find a dressed deer (which is ready to be processed-hide, head, guts, legs gone) will transpire in the 60% range of meat. Again these are approx. numbers not actual, other factors are involved and one deer might be 38% while the other might be 30% of live weight...obviously with equal weighted animals the meat take will be different, therefore no exact calculator or tool to accurately perdict what you'll end up with, just a rough guess that i know of. Sorry like I said it is the best I can do and I won't profess to be the expert either. I have butchered all my own game for a number of years and yet many other guys as well. 100% honest I hardly ever weigh animals or meat anymore, it really isn't that important to me doing it myself and for those who ask me to it for them they know they are getting what they brought in. Maybe somebody has a better tool out there and will provide it for you, but this has got me close in the past.
