Forgive me if this is a question that has been asked and answered. As mentioned, I have the Lee 4 die set in 9 mm, and the 4th die (with carbide) is the factory crimp die. If the bullet seating die will apply a crimp, and the instructions indicate that it will, do I really need to use that 4th die, and why? Thanks. And I should mention that I've reloaded for years on rifle and revolver ammo, but never on semiauto ammo. And as for equipment, I use a single stage press and don't want to run all that ammo through one more die if it isn't necessary.
