Hard to tell what the variation is now? 3 shots is not statistically significant. The first load could still have more variation than the first, but three shots just randomly didn't happen to show it. Harder crimps will tend to improve it. Some find that seating primers extra firmly improves consistency, though that is most likely just a way of insuring no inadequately seated primers are present. Higher charge cut into it, too, but if you are after a target velocity load, you likely don't want that. Going to an even faster powder can get you the same thing.
