I use a lee 4 die kit ... I use taper/ crimp die. I put a bullet in the die and screw it in till it makes contact with the bullet, then back the bullet out then screw the die in a 1/4 turn.
Is using the last die even necessary? I size and deprime then bell the case just enough then seat the bullet then crimp the case to debell the case. I am new still and learning the lingo but I believe I don't crimp but I tapper
