Frist off congrats on the ALMOST coyote. lol i would say from my cases he will come back to the area. i would set up a bit different tho. move the caller and not be so far from it maybe. id say 100 yards is distance enough but with a 243 distance isnt a huge deal. I would say 2 weeks or a little more would be about enough time. but like i said if you wait and change it abit he may not remember his past experiences. you may also change your call sequence a little.
