You have decided that you will shoot the first mature elk that gives you a shot, you have located a herd,moved in on them and see a couple of cows milling around at 75 yds. You get ready to shoot, give a couple of soft mews, and a big raspy bugle booms out just beyond the cows. At your call one of the cows heads your way and is almost in range. What are you going to do?
