For 200 - 300 yd shooting coyotes a 223 shooting 40 gr Nosler Ballistic Tips at about 3700 - 3800 fps works just fine. I have killed numerous coyotes within that range using that combo and all have been one shot kills, it drops them dead right there. Just in case you are interested in saving hides I have never had an exit using that combo either.

223 Rem, my favorite cartridge - you can't argue with truckloads of dead PD's and gophers.
