after having a successful session of shooting at a normal round target I put a 5 of hearts target with hearts at the corners and one in the middle about the size of the face of a watch. I couldn't come close to the center heart although my shots tended to be close the corner heart.After three of those type shots I decided to re-think my shooting and started to focus on the center of the target where I knew the big heart should be. My focus was more on the center of the target than that fuzzy black thing or things out there. Amazingly my shots fell in about where they should be and I started cutting holes within about 1/2 inch or less of the center heart. Do't know if it was an optical illusion or just bad eyes going out at 60 yards but it was fun finding out what worked for me.
