You can also pause at the top of the ram stroke for 4 or 5 seconds and this will greatly reduce brass spring back. The more the case neck and shoulder are work hardened the more spring back you will have that effects bullet grip and shoulder location.
The best part about the Redding competition shell holders is you never have to touch the die to adjust the amount of shoulder bump.
