Where I live we don't have any coyotes, just fox. But for my fox hunting I really like my .17 Remington. Generally it goes in one side and leaves a big bruise on the other side, but doesn't go all the way through. Occasionally it does and then you get a pretty big hole. When I used to go coyote hunting I used a .220 Swift and liked it quite a bit. FWIW a .220 Swift works pretty good on our Blacktail deer though.
