I attended a class where they taught that you only needed to shoot at no more than 5 yards, on smaller and smaller targets to learn how to shoot at longer distances. I was skeptical of the claim as distance multiplies the movements at the muzzle. So, I challenged the instructor who had a female student shooting 1″ groups at 5 yards to have her shoot at a 25 yard target.
According to his claim, she should have all center mass hits with no problem. She shot 5 rounds and missed 3.
