I think the best thing to do is first measure some factory fodder and you can get a idea of what your gauge is doing.

The ideal world I think 0 on the gauge is about max of case headspace ? the minimum is -.XXX depending on the cartridge.

Once you get a base line you can now adjust your dies to get brass back to thes "0" or adjust your dies to push the shoulder back .003-005" or so.
