You don't need to crimp but if you want to.

1. Turn the die up a little so there is no possibility of crimping.

2. Put a case/bullet in and little by little turn the seating stem down until the bullet gets seated at the point you want to crimp. Run a few bullets through so you have a few bullets to work with on the crimp later. You now have several loaded but uncrimped bullets.

3. Turn the seating stem way up so it is out of the way completely.

4. Raise the press with a loaded bullet and turn the die body down until the crimper contacts the case, lower the press and turn the die down a little at a time, maybe 1/8 turn, raise the press fully to crimp and lower to check crimp. When you achieve the correct crimp lock the die in position. Might take a couple bullets and attempts to check and confirm after locking the die. Now you have a loaded and crimped bullet.

5. Crimp is set and die is locked in position, put a crimped bullet in and raise press, lower seating stem until it firmly contacts top of bullet and lock seating stem.

6. Verify it is all working with a few loose bullets and cases.

I was having trouble with setting the crimp with mine. They would run fine in my xd but would jam in my 1911. I got a lee factory crimp die and it solved all problems. I seat the bullet with the rcbs die and crimp with the lee.

It takes a little bit to get them adjusted, but I've been using the seat/crimp die in all reloadings (9mm, .38/.357, .44 and .45acp) for over 20 years.

All dies set up using the method tundragriz posted.

That is the method I have used for all calibers, rifle and pistol. You can get alittle variation in amount of crimp IF your case lengths are not exactly the same.

I have found over a few hundred thousand auto pistol reloads to seat bullet and crimp in two different steps. much simpler and less headaches. If it means setting your die to seat and then reset to crimp and unscrew the bullet seat stem

I have found that it is easier for me to use a taper crimp die as a separate step. I use the Lee die on 9mm, 357 Sig and 40 / 10mm.

The Lee dies are cheap and easy to adjust.
