I agree with that note, but I also see a major change in the radius at the edge of the primer.
When you look at the before and after there is a big change where the primer meets the case.

Primer edge radius is going to change in loads that produce around 35,000 psi. We should not be looking for the "after" photo to look like the "before" photo with only the addition of a dent in the center.
But, the AMOUNT of radius change is hard to correlate with peak pressure, because it has a lot to do with how far the primer protruded from the case when it was fired, before the case moved back against the breachface and reseated it flush. That changes with primer brand, case brand, powder and gun.
So, about all I can say is that bozhoz's fired primer radius doesn't look like trouble to me.
