I have experienced one deer and it went this way, last Oct, day two... and it tasted excellent...one reason I am hooked on hunting.
Shot the deer at 8 AM Sunday.
Boned it out on the spot without gutting it. Spread it out on coats and extra shirts, etc to cool off.
Carried the meat down the hill, and had it in game bags and in the cooler by 12.
Drove home the next day, Monday and put it in the fridge.
Cleaned it up, what little cleaning there was to do, and cut it up Tuesday night.
No plastic, no hanging/aging on purpose, other than the two days to get home, but was always kept cool and dry.
It was all excellent. Roasts, steaks, ground for tacos, soup, etc. We just treated it like beef. We were with an experienced hunter and just followed instructions until we drove away from the campsite. We went with our guts the rest of the way.
If there is anything I am missing, let me know. Like , even what we may have sone right... It seems like we must have done the right thing.
