Roskoe,I have a very old chrony and though it has work well overy the years I do not trust it. Set up at 25yds so that the sabots dont hit it it shows a bit more than the figure you mentioned,I wish that they would bond them I am concerned about the terminal ballistics. I shot a big coyote with one and it left a hole you could put all your fingers and your thumb on exit, I plann to do a little experament when I go hog hunting if possable and I will post results. Lee
