No wad pressure is required for the modern wad. Just have the machine push the wad down far enough to allow the full shot load to fit in and a nice clean crimp to be formed. It is easy to do with a little adjustment. Some minor shanges may be necessary to produce a clean neat crimp if you change wads or shells.
Pull the handle down, loosen the jam nut on the wad ram, turn the wad ram in until you feel it start to compress the wad, tighten the jam nut.
You cannot put any pressure on a plastic wad in a plastic hull that will remain after the wad ram is removed. Putting a slight amount of pressure on the wad with the wad ram assures that it is seated on the powder charge and keeps shot from spilling out when the press indexes.
<blockquote><I>"Or you can fully depress machine and use a pencil to push up on the hull. If it moves a bit the wad is loose. I just turn mine down till it wont push it up easily."</I></blockquote>Assuming (yes, bad word!) that the correct wad for the powder and shot load is being used, all that needs to happen is that the ends of the wad petals get down to about the inner ends of the crimp folds. Once the shot has been dropped, doing the crimp will push the shot and the wad down into the hull as deep as it needs to go.
