If you are using Lee turret press or similar, keep factory lock rings, install in turret, adjust to suit, tighten securely and never fool with again. Just use another turret for each other caliber. Some calibers I have three sets of dies, some even four. Will set up one set for turret press, one for progressive press and never change. Third set is for when I want to use a single stage press building a specific load in low volume for a special task. Then on like .38/.357 and .44spl/.44mag I have one turret in special, one in mag, one set for progressive in whichever of the two I volume load for and then the spare set for single state press. Know it sounds goofy but every once in a while find a die set.on sale, someone selling all their equipment and and so on so over the years they pile up. I actually have double sets in some calibers I have never owned just from buying out quitters of estates.
