All the talk about a great first shot is fine for deer; but I hunt elk by myself and do not want them walking to the bottom of a ravine before they fall down. I want a second shot available fast as they are tough and I have had heart shot cows walk off for almost ten minutes before they dropped. I had one cow with a double lung shot and a second one made when she was running at about 100 yards that took out the liver walk and run over a half mile before I finally managed to head shoot her. She saw me and had the adrenaline pumping apparently. That is why I am presently using Black Mag'3. I have such severe crud rings with 777 that I refuse to use the stuff. That second shot was within 30 second or less of the first shot which would be impossible with 777 in my rifle.
