I have eaten several mature bulls from Alaska and the meat was delicious. Smaller bulls and cows were a little less gamey, but there was little difference. Moose, in my opinion, is the least gamey of all wildlife. My favorite is a crockpot roast with lots of garlic, salt, and pepper. Throw in potatoes, carrots, and a brown gravy for everything and you are good to go. I have never had the pleasure of eating a shiras though.
