I've never been a real consistent shooter with snub nosed revolvers. I do alot of dry fire practice and can shoot double action and keep the sights pretty still. Today at the range it looked like it was going to be a rough day, my shots were all over the place. So I decided to try an experiment of sorts. Without looking I loaded two rounds into the cylinder, gave it a little spin and closed. The first pull of the trigger fell on an empty chamber, and it became obvious that I had developed quite a flinch. I repeated the exercise, varying the number of rounds I would load, but always leaving at least one chamber empty. It was remarkable how quickly my groups shrank.
This is method is not my idea, I've read about it before and hopefully it can help someone else. Just wanted to pass it along!
