Does the primer supposed to go all the way into the little cup on the primer attachment. Mine would not fit in the cup so i used a die bit aand reamed it out some now it starts in the cup but not all the way? Also i cann not get the heigh to go as low as what is called for in the manual. from the bottom of priming slide to top of cup says to be 1.215 to 1.220 i put it in a clamp and fully compressed it and the tightened the set screw and when i relase clamp it goes back to 1.230..Any ideas.
