For the SEATING die?? You never run the seating die to the shell holder. The Hornady die has a roll crimp built into it. So... it contacts the mouth to make the crimp. If you dont' want to crimp the case... put a shell in the press, and run it up. Then... run the die in, until it touches the shell (brass)... and back it off a little.


IF... you want to crimp then:

1) make sure all your brass is the same length
2) Seat a bullet to the proper depth
3) Back out the bullet pusher, and then start to adjust the die down, until you get the crimp you want.
4) Once the crimp is set, then turn the seater in until it contacts the bullet.


With that said... I find that most small brass is too soft, and if you try to use a roll crimp, it will crush the shoulder. But it works great on straight wall pistol brass.
