You can accomplish the same overcrimping with a taper crimp die. If not adjusted right, you can almost make a 9mm loaded round look like a 357 Sig round. If one follows the directions on an FCD die, it's pretty hard to screw it up. The same can be said for any die. Ya gotta be smarter than what you are working with. I know people than can tear up an anvil with a rubber hammer. There is nothing wrong with the LEE FCD die if used correctly. Likewise for the TCD. I have both, but use the FCD die way more often, and have no issue with it whatsoever.
