You need to use a little item made by Forester....(I think) that has three brushes and the container holds powdered graphite; brushes fit various calibers! If the button on your depriming pin is a little rough, the case mouth...when run down on one of the brushes picks up graphite and applies it to the interior of the neck. This application lets the case, when being pulled downward slide much easier over the sizer button. What can take place in some instances is the shoulder of the case can be pulled out of alignment because of being hard to slip over the sizer button. Also...putting an 'O' ring under the locknut on the resize die and not 'hogging down' the die (letting the die float) against the press helps!
Wilson inline seating tool is a valuable asset!!
