As I said, it will likely run about 5000 psi higher. Perhaps I am being overly cautious, but I would still find five more cases and load 2.5, 2.0, 1.5, 1.0. and 0.5 grains lower and fire the five in that sequence, just double-checking for pressure signs after each step. Since 5,000 psi is less than the 15,000 psi increase you need to get to proof load pressures, it should not cause an issue, but I like to treat the old girls nicely. No extra stress.
