Well, my huntsmans barrel has a total of 16 rounds thru it. That is sighting it in at 75 yards and breaking the barrel in. About 4 clicks to move it to the right, and about 40 clicks to move it up and it is right on. I am amazed at how well it shoots out of the box and how easy it was to get about a 2" pattern. I still need to shoot some more because I want to try a heavier charge, but if I don't, I am happy with it.
