Move it to pattern. Easiest way is to put a dot on 4'X4' piece of cardboard, paper, etc. Shoot at the dot on a solid rest. I use sand bags. Go to the paper and put a dot in the center of your pattern wherever it hits and is the most dense. Now go back and put the gun on the sandbags and put the dot where you aimed the first time. Have someone move the red dot until it's in the center of the dot on your pattern while holding the gun as still as possible. Easiest way to do it.
