I have some beautiful venison loin that I've been experimenting with with varying results. I've tried 131F for 2 and 6 hours so far and want to try a longer cook ~ 24 hours. Anyone have any experience with this? My attempts so far have been delicious and nicely medium rare but not as tender as I'd hoped. I'm hesitant to try it willy nilly since my venison supply is dwindling and I don't want to screw it up. I've looked and haven't found too much on longer cooks, just the shorter 2-6 hours. Any help appreciated, thanks!
