I've always processed my own game beginning with rabbits, squirrels and quail then moving on to deer and elk. I read a couple of articles on it then just started doing it. We de-bone everything. With Venison or Elk, you want to trim as much of the fat off as you can. Then process it as you want. (Usually steaks, roasts, stew meat and ground meat.) We ground our meat for years using a hand grinder. I bought a good electric grinder about five years ago and I love it. Look up some seasoning ideas online and try a few of them out.
With bears we usually make them into roasts and sausage.
