[QUOTE=akoda;140750693]I can seat with my 38/357 seat/crimp die, then crimp with my luger die? How do you crimp on parallel sides?[/QUOTE

1.) Yes you can seat with your 38/357 die , apply no crimp .
2.) You taper crimp with the 9mm Luger seat/crimp die ,( crimp but adjust not to seat bullet any deeper )taper crimp just like you are loading 9mm ammo because the bullet you are using is a 9mm bullet designed for 9mm Luger , 38 Super etc.
The taper crimp doesn't roll the case edge into the smooth bullet side...it just presses the case against the bullet .

On bullets with parallel sides , like plated and cast 9mm Luger bullets , when loading them in 38/357 I simply use the seating / crimping(taper crimp) die from my 9mm Luger set in place of the 38/357 seat/crimping (roll crimp) die .
I don't use powder coated so I can get away with seating/crimping in one step ...But with coated bullets you will have better results seating in one step with your 38/357 die and in a seperate step applying a taper crimp with your 9mm Luger die . Less chance of the coating getting cut or scraped .
