| 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 visible.
If the caliber you wish to load requires one of the other slots on the shellplate (see the
caliber conversion chart to the right to be sure), you may change this by first loosening
the brass-tipped setscrew (Figure 5) at the top left side of the shaft, just below the
shellplate platform, with the supplied 1/8" hex wrench.

Next, loosen the shellplate bolt with the 1/4" hex wrench.
Then reposition the shellplate cover to display the slot you desire to use. The shellplate
cover has two dimples (Figure 6) to help you align it with the shellplate.

500 shellplate cover. |
Tighten the shellplate bolt with the hex wrench – then back the shellplate
bolt out about 1/4 turn so that you can rotate the shellplate easily. There should be no
looseness or "slop" at this point. When you rotate the shellplate, you should be
able to feel and hear the shellplate "click" into place. Re-tighten the
brass-tipped setscrew under the shellplate platform to prevent the shellplate bolt from
rotating as the shellplate is indexed. |
