Typically,crimp to .002-.003" smaller than the maximum case dimension on the cartridge drawings.

While some die sets use a combination bullet seating/crimping die, the 9mm, .40 S&W, .45 ACP, etc use a separate crimping die that produces a "taper crimp". If your die set doesn't come with one (some of my earlier sets didn't) you may have to purchase it by itself. When setting it up, just follow the instructions. Don't OVER DO the crimp. It should just be a few thousandths difference in the case where it crimps, and the case neck.
