I've been boning my own for over 20 years. Good tasting meat starts in the field. I like a nice double lung shot that drops the deer fast. When gutting in the field I keep the opening small to minimize leaves, dirt etc. getting in the body cavity. As soon as I get it back I wash off any blood inside and out. I keep filling the body cavity with cold water to help cool the meat. Aging is great if you can keep the deer body temperature in the mid-30's but that is usually difficult.
When ready to bone out I hang it in the garage by the back legs by a gambril (sp?). Once skinned I start removing the meat from the neck and the loins. My family is pretty well 'deered out' so most meat goes into burger. The loins are good so that is where I usually get any steaks and roasts. I remove all muscle sheath, fat and tendon. My deer steaks and roast are pure meat. I'll often leave the loin in 4-6" sections so I can cut as desired when thawed.
Next I remove the front legs take in the house and debone to become burger.
Don't forget the tenderloins inside the rib cage along the backbone. They are the most tender, delicious piece of meat on the animal. What they lack in size they make up in quality.
Last are the back legs and rump. I tie one to the gambril so that when I remove the first one the second doesn't fall to the ground. If you want more roasts, steaks or other good cuts this is where you get them.
Even with hamburger meat I remove as much fat as possible since I don't really like the flavor and it solidifies quickly as the meat cools after cooking. I usually have beef tallo added for the burger so it sticks together for burgers and adds flavor.
I usually freeze the roasts and steaks myself in zip-loc freezer bags. The cut up meat for burger I take to a locker have them add the fat, double grind, wrap and freeze. Saves me lots of trouble for a few bucks.
You can take as much time as you want with the meat. I shot an antelope in Wyoming years ago. The game warder who had directed me to the ranch insisted that I bring it to his place for butchering. Then he insisted on helping. When we finished he and his wife insisted we stay for supper with their family to enjoy a wild game meal. Part of the reason I bring this story up is that he said when he butchers his own animals he removes all fat and all muscle sheaths (the whitish covering) from every muscle. He did so on a shank on my antelope. It took him close to half an hour to do the shank. He said it usually took him 10-12 hours to bone an animal and end up with absolutely pure meat. Needless to say we didn't do the whole antelope that way.
I take a lot of care with the stuff I bone but no where near that much. Does show how far you can go if you have the time and energy.
