I have shot an animal more than 3 times. My last elk needed 4 - 160g Partitions to get him to fall over dead. My theory is keep shooting them until they fall over. Heart/Lung shots don't waste any meat. Since my last elk was shot over 300 yards away (no chance to get closer) I require my rifle shoot as close to MOA as possible. Since there have been times when it was needed to shoot an animal more than 3 times I like to have the confidence in my guns ability. When you factor in that MOA at 300 yards is 3" and factor in hunter error, wind, and excitement of the moment, 3" can easily double. I respect my game very much and wouldn't have been comfortable shooting that animal with a 2 MOA rifle. Nothing worse than a wounded animal that has to suffer unduly, or worse, get away. Since long shots are a possibility out west where I hunt I need an accurate rifle. For hunters in timber or other denser areas a 1.5" or 2" rifle at 100 yards would be just fine assuming shots won't exceed 200 yards.
