First of all, my compliments on very fast shipping and good assembly instructions. It comes painted which is a big plus. I had a minor issue mounting the popper bracket as there was some raised metal close to the bend that prevented insertion of the bolts. A few swipes with a rat-tail file solved that problem. I did not have a hammer with me when I took this to the range the first time and could only insert the stakes about half way by hand. This is the 1/2" steel target that I set up at 570 yds. The first shot was with a 185gr 7mm Rem Mag and the entire target did a backflip simulating the real thing I guess. A subsequent trip put a lot more shots on target with the expected movement. I will note that if the bullet strikes the edge of the popper, there will be a burr raised on the edge. Hits off the edge do no damage. Count me a happy camper on this target.
