+1 What he said.

That's why they make guages. If cases were all that accurate, I'm sure the factories would use brass and save the $$$ for the guages. In your case it's understandable and pretty much the only way to go.

Remove the ejector, and just add something to the base of the case that is .002" thick (or the plastiguage on the shoulder area) and you should be good to go.
