Seat a bullet without crimp, look at the bullet point on, see if the brass neck is touching the bullet all around, if so, you probably don't need any crimp. If there is a slight gap, adjust the crimp just enough for it to close that gap.

Install the die and adjust the body of the die until it just touches the brass at full height in the press. Should be just about right, if not, maybe another .5 turn on the die. Then work on the bullet seat depth.

I'll measure my COL tonight and see where mine are compared to yours, I'm curious. I might be screwing mine up!
