I have one die set for revolver that I only could get a 3 die set. I seat, and crimp in the same step. It is not bad as long as your brass is close to the same length.
Adjust die to seat without crimping. Then adjust to the level of crimp you want. Use the cylinder of your revolver as a gauge to assure the round will chamber. Once you have a round you are satisfied with. run the completed round into the die then screw seating stem down till it touches the bullet. Your die is now adjusted. Try another round, and see if chambers in your cylinder. If yes then keep going till you run out of components.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
