As R93 said, you won't see normal pressure signs like a standard case shows. My 257 AI would indicate high pressure with a stiff bolt handle and the primer still looked ok.

24" barrel. What I couldn't figure is 44gn with the LRABs was fine but 43gn with the Amax had stiff bolt lift. I think it must be because the LRABs were seated with 20 thou jump but the AMax's are into the lands as I didn't change the seating depth from the LRABS.
