Either gun will work fine. You're not going to be taking more than 1 shot more than likely (slight chance of taking 2) because coyote don't like their own dead, so if you get one, i suggest leaving him there or hangin it up so they don't come back. And about the one shot, once you shoot into them, they disappear so if you don't want a dead carcass layin around to keep them away, get some buddies together, as mentioned earlier, and try to get more of them.
