There aren't too many bullets out of a 223 that won't kill coyotes long past 300 yards. I've pretty much only been loading 40 grain Ballistic Tips for years and they knock a coyote in the dirt right quick. Starting to test the 50/55 grain Bt's and a bunch of the 53 Vmax, and they seem to about as accurate as the 40's, but I'm not sure how they could be any more deadly.....
