Head, neck or heart shot animals die with all the blood remaining in the blood vessels. Attempting to bleed your game by slicing the throat after the heart stops is a waste of time. Except for big bears, there is no need to keep shooting at an animal after it has been well hit once in the lungs. He was right. It seems to take almost two minutes for a lung shot moose to bleed out into the chest cavity and fall down.
More shots just make more holes, a big mess, and wasted meat.
On big bears keep shooting until the bear is down and stays down. Approach all downed big game cautiously from the rear with your rifle chambered and in a ready position. Stop well away from bears and moose and look to see if there is any regular movement of the chest due to breathing. The Hunting Camp Nothing can make or break an Alaska big game hunt more quickly than the quality of your camp. I suggest that new Alaskan hunters put together a backpack camp weighing 40 pounds or less, including tent, sleeping bag and pad, cooking gear and dried food for a week.
