RE: grind my own?
Last month I helped a bud make a small batch of wild hog sausage...to make, you know, room in the freezer. We got a recipe for breakfast sausage, and went at it. It came out so well, that we plan to grind up a lot more pork for sausage as a nomal part of processing. BigGuy01 is right, but his advice came a little late...and we're happy about it.
Good luck with all your game cooking experiments & experiences.
