I use the Lee 3-die set for .45acp and don't know anything about the factory crimp die.
That said, maybe my process can be helpful anyway.
I start by screwing the seating stem all the way in to the bottom, then set a case and bullet in the press, and CAREFULLY bump the bullet down into the case in little steps... check, bump, check, bump, measure, etc without pulling the lever to the full stop obviously. When the bullet is right where I want it, unscrew the seater plug fully. Then run the ram all the way up and screw the main body of the die down until it contacts the case, and add another half turn or so. Just like setting the bullet seat depth, make a bunch of small adjustments until the crimp looks and measures just right. Now run your finished round up into the die, and screw the seater plug down until it makes firm contact with your bullet. The seat/crimp die should now be fully adjusted, check the next couple rounds and tweak slightly if needed.
