pressure signs from primers

[Shadow9mm]

working up some hand loads for my 30-06. Ignore the cratering, its an issue with the gun i am dealing with. shooting varget with remington 9 1/2 primers speer gold dot 150g bullets 0.011 off the lands. primers look normal up until 52.5, after that 53.0 and 53.5 both seem to be flattening and the dimple from the primer does not seem as deep. I am not super familiar with judging flattened primers as pressure signs I have never really run into this, but i know it means they are on the warmer end. How do i tell if I am ok or if I should back it off? in order
51.0 / 51.5 / 52.0 / 52.5 / 53.0 / 53.5 (listed max 53.6)

51.0 up close

53.5 up close

Your fired primers look entirely normal to me, other than the "cratering" you mentioned which looks like your firing pin hole in the bolt is bigger than your firing pin.
Go here and look at the bottom of page 12 for a picture of a flattened primer:

thanks. been researching primer signs, think its mostly normal too, good pressure but not too much. wont go above that load. dealing with the cratering, Thompson center said its not normal, think its an issue with the firing pin channel, sending it in to them, just waiting on a label.
