Finally, I fired my new S&W Model 10-7 bought a couple years ago and observed that it shot 8 inches left of point of aim. Ammo was factory 158 grain. Distance was 25 yards. Two other shooters had the same result. I called S&W, and a nice Texan answered the phone in Tennessee. He emailed a Fed-X return slip, and I shipped it to Massachusetts. Clocking the barrel more to the left will move poi to the right. However, I doubt that it will move the group 8 inches. I hope that I get back a correctly repaired revolver. Dealing with Smith was pleasant.
