I have done some searching but can't seem to come up with a definitive answer. I have read in a lot of places that it is recommended to taper crimp 9mm rounds in a semi-auto (XD9SC to be exact). I have the Lee 3 die set and can't seem to understand or figure out how to make this crimp with the bullet seating die? Do I need to do this process in a whole different step after I seat the bullet or can I adjust the die so it will seat the bullet and crimp the case at the same time? Or would I just be better off bying the Lee Factory crimp dies with every round I decide to make?
