6 Changing Shellplate Position Your AT 500 is shipped with the “universal” shellplate installed. The “universal” shellplate has four shellholder slots: #1, #2, #3 and #5. This allows you to reload a wide variety of calibers. All AT 500 reloaders are shipped with the #1 slot visi- ble. If the caliber you wish to load requires one of the other slots on the shellplate (see the caliber conversion chart on page 3 to be sure), you may change this by first loosening the brass-tipped set screw (Figure 5) at the...

Do this by loosening the set screw and removing the large primer cup and pin from the primer bar. Install the small primer cup and pin. (Figure 7) Do not tighten the set screw yet.

Thread the taper crimp die into the toolhead until it comes in contact with the cartridge. In 1/4 turn increments, thread the taper crimp die clockwise while you move the handle up and down, until a crimp appears on the mouth of the case. An average crimp should be approximately .002 smaller than the case diame- ter. (Figure 20)...
