I'm not sure I understand why a certain caliber is used, when the outcome is in such doubt. The Hummer is a wonderful caliber, but like every other caliber, it doesn't do it all. We all agree that we hate losing or wounding an animal, to die a slow agonizing death, so why not use a caliber that is proven on whatever game your after. Some say they have stopped coyotes in their tracks with the HMR. Many have said they have lost them with seemingly good placement. A number of folks have lost fox, with the hmr, too. This just adds up to inconsistancy, thus a poor choice in taking a gamble, or experimenting on animals. The HMR was never intended for coyote. It was intended for small varmints and paper.
