The profile crimp is a crimp that uses a taper crimp and a roll crimp combined. You will want to get you seating depth set first. The ease into the crimp. You do not want to much crimp.
Once it is crimped you will not move the bullet.
My personal feeling is that it was designed for jacketed bullets in use with BIG BORES, and ARs. The jury is still out for a decision about the use of the profile crimp and a cast bullet.
Edit : Forgot to add that you can adjust the crimp too much or too tight and it will distort the bullet and create the look of a Heeled Bullet. So start off light and see if you get bullet jump and the then proceed to adjust accordingly.
