As others have stated. Expand to 7mm, load up and go about your normal business.
When I first fired my necked up 6.5/284 brass in my 284 subsequent loadings of the formed brass showed virtually no change over the first firing.
If you're worried about some change after the first firing just do a quick zero check on the 2nd loading.
