Get him shooting with his dominant eye. This weekend I put in a lot of time with a BB gun and getting my left handed left eye dominant 5 year to shoot left. I made him have bad habits and let him shoot for the last year right handed. I threw the gun in a miter saw cut her down to his proper length of pull. After some complaining and one large tantrum he was hitting the cans every time and couldn’t believe how good he could shoot using his dominant eye. Now to break him shooting a bow right handed.
