Was able to easily get on target at 100 yards by removing the bolt and sighting through the bore.
The bench setup was not optimum, with a shaky rest. My eyes need more than 3X, a big fat circle is not the best target, and the Leupold is not parallax free at 100 yards. But I was very pleased with the overall first time performance using Nosler 110 gr. AccuBond +P.
