Everything went perfect. Boresighted in my garage then went to indoor range. First shot was about 3 left and 2 high at 33yds. Adjusted then perfect at 33yds. Sent to 100 yds. Knew it would be high. 3rd round was about 4.5 high at 100. 4.5 MOA adjustment and 4th round was perfect. Then shot 4 groups 3 rounds each. All between ¾” and ½” Just makes you smile”.
