I love my 223,I have killed them from 3 to 290+ yards with it and usually within 90 yards they like to get close in KY due to the hills and hollows and broken farm and forrest land,you will be able to kill them at 300 yards with it,my ruger loves the black hills 52 grain soft points and they dont explode like the ballistic tips,I like the hornady's for ground hogs,but they usually tear up some fur on coyotes.Good luck and good hunting!!
