[QUOTE="Canadian Bushman, post: 920872, member: 41122"] Im not arguing this. This is true for every press with any die. Im saying creating more resistance as the press cams over by screwing the die down more, is not necessarily pushing the case further into the die. This is not true and it is beside the point i was trying to make. Some cases, when being sized in a particular die, do not need the die to contact the shell holder in order to have the headspace bumped back enough to properly chamber in the rifle they are being sized for. [B]If you set up your die by contacting it to the shell holder, there is a good chance you could be overworking the case.[/B] The "CAM" is the most upward part of the stroke of your press's arbor. When you reach this point the press handle is moving the greatest distance relative to the distance traveled by the arbor. You always want to run through this point on any press operation because it assures your arbor is reaching its highest point with the greatest amount of force. This is regardless of the amount play you have in your arbor or its alignment to the die. If the seat is contacting the bottom of the die at this point and you are feeling resistance in the handle, chances are the case is as far into the die as it will be able to go. In my opinion screwing the die down any further is only stressing the components of your press. You would benefit more from running the case through the die a second time or even removing material from the base of the die or the top of the shell holder, than you would by screwing the die down any further.
