Fair point. My understanding of swaging is that it trues up primer pockets regardless of dimension, ie cold forging the brass back to spec.
This is given that they're too tight/ distorted, not too loose.

I'd say that what you've posted above should be his first stop, before/instead of doing as I have suggested.
