28 Nos Flat Primers

Personally I think you are making a mountain out of a molehill. Factory ammo is never loaded that will cause an over-pressure. From what I can see, this is not an issue that needs to be discussed. It is what it is with this rifle and if there are not bolt lift issues most likely can be ignored. If there are bolt lift issues with factory ammo you have a chamber issue.
All the pictures I posted are 160 and 175 factory loaded nosler ammo.
 
Update on this (from the OP, there are multiple people asking questions on this thread). Did some more tests with factory ammo.

160 grain "dirt nap" from fierce - very slight flattening
160 grain nosler ballistic tip - no noticeable flattening
175 grain ABLR (not from recall lots)- flattening similar to handloads.
