Yes. Most, including myself, shoot a large (36"x36") piece of paper or cardboard with a dot to aim at in the dead center. Aim at the dot and shoot. Draw a 10" circle around the densest portion of your pattern. If you are lucky, the dot you aimed at will be dead center of that. If the dense portion doesn't center around or slight above your dot, you will need to adjust your sights (or add some adjustable sights if you don't have them) to where you POA matches your POI.
