I have always used a 22 or 22 short. Draw an imaginary X between the eyes and ears and shoot just over the X. They will bleed but typically coyotes need to be washed after fleshing anyway. Add a shot of Woolite to the bath you give them and they will really look good.
MN Trapline Products is EXCELLENT to deal with. Great people that know what they are doing and have incredibly fast shipping. You can't go wrong with them. Try their MB-550's for coyotes and that is all you will ever use again.
