I live in Central WI. and have hunted for 25 years on my five acres and a few farms in the area. First of all, you will not get as much meat off of a deer as you might think. Deer are not muscled the same as domestic animals engineered for meat production. That's not to say that you won't get some very excellent cuts to put in the freezer, but it's not like a beef steer or a whole pig. So don't be disappointed. Second, learn to gut, skin and butcher your own deer. Take your time, the deer isn't going anywhere. It's respectful to the animal, because it shows that you want to make the most of it in the best way. A good, clean kill is only the beginning. Also, the cheapest I've seen butchering fees is a hundred bucks or more; save the money. When you do it yourself, you get the cuts you want, trimmed the way you want and you have the satisfaction of being a true sportsman.
When you butcher venison you can be picky and remove the tallow and silverskin that can give venison an off taste. When people say they don't like the taste of venison, it's probably because someone didn't do a good job of trimming. When you take your deer to a processor you can't be sure of what you get back. I want my venison, butchered my way, because I know how it was handled and how well the carcass was taken care of.
I don't care to mix my venison with other meats. I don't make sausage or "hot sticks". I cut a few roasts, cube stir-fry meat, tenderloin tips, backstrap butterfly steaks and bone everything else out for ground venison. It takes a couple to get the hang of it and a couple of good filet knives.
I've had great success with a scoped Mannlicher-Steyr chambered for .270. I reload all my own hunting ammo. I use the same powder, bullets, primers, consistently. We can hunt with rifle or shotgun in my zone. If you have to use a shotgun, I feel a rifled slug barrel with sabot slugs is the best way to go. I usually try for shot placement behind the the front shoulder. it takes out the lungs, maybe the heart (too bad because heart and liver are delicious). and wastes little meat. I should say that I hunt for meat. I have antlers on the wall, but that wasn't what I was after. A nice big doe is just fine by me.
I've never heard of anyone getting a deer sitting in the house. The truth is that you have to dress for conditions and be out in the woods where the deer are, usually for hours at a time (I'm a still hunter). I bring sandwiches, snacks, a thermos, a comfy cushion, and a pocket radio with earbud to keep from going completely nuts. I plan on going out early and staying out until I get something or the day closes. As soon as you give up and go in, you'll hear a shot and it will be a neighbor or someone else in your party shooting a deer that could have been yours.
