If you are getting good groups, you have a sight alignment problem. If you have a cylinder problem, your groups will be terrible. To check the cylinder alignment, you will have to take a rod that is close to bore diameter and run it down the barrel. It there is an alignment problem, you should be able to feel it catch on the throat of the cylinder on one side or the other. It could just be that your sights at not looking where the gun is shooting since all of your groups seem to be in the same place. I assume you do not have adjustable sights or you would have tried that already. With fixed sights, you will have to have someone turn the barrel in slightly, and that will move the group to the right. By carefully filing down the front sight you will raise your group. 44 Man
