I discovered something I didn't know before. I have been shooting since I was a teenager. As I am right-handed, I always aimed with my right eye. The other day at the range, my groups were looking like shotgun patterns! Little exaggeration there, on my part Anyway, I decided to start aiming with my left eye. Lo and behold, all my shots started gathering in or very close to the X-ring! This was no fluke as I tried this same technique from all the distances I shoot from. It also should be noted, the only thing changed was the eye I was aiming with. Same trigger technique, stance, etc. The only stance modifaction was tucking my right cheek against my right shoulder. I couldn't believe how much my accuracy improved, especially at longer ranges. Also, my sight picture is much clearer now. I guess I am left-eye dominant and never knew it!
