The 204 is more than adequate for coyotes,mine has a 1 in 10,Thompson center venture. I don't reload ,I've found Hornady and HSM make more than enough loadings for various applications. The 39 Blitz King will be your best bet,@ 3857 fps,and a high BC of 0.287,at a quarter mile it will drop a coyote if you can hit em.I've killed dozens in the last several months,check out LRHF,you'll see ,can't figure out how to load pictures here and have given up.My go to round in Ohio is Hornady 26 gr superformance @4400 fps,out to 300 yards,most shots are 200 or less it flattensem. You'll love the 204,it's laser.
