I agree with steve863. Meat does not age so fast that the quality becomes an issue unless it sits over night in hot woods. Take a good clean kill shot rather than the "MEAT SAVING" shot.

Me personally, I like a high shoulder shot. Breaks the animal down immediately. Possibly breaking the neck.
Clean meat, vac pack and freeze right away. Never soak in milk or water. Always tender and clean.
Good Luck!
