I double wrap mine in freezer paper, I squeeze every bit of air I can get out of it out, and then wrap it a second time. I have had some for over a year and as long as I wrapped it right it has been fine. Murf the freezing in water thing I do with fish, it works great as long as you make sure they are totally covered with water, I would imagine as you said that would work well also for deer.
