I can recall from 2005: There are two types of gun; Those that are stronger than the brass and those that are not. The guns stronger, I can incrementally work up until I see brass start to fail. If the whole brass case head fails there may be secondary failures, so the case must be checked carefully for small changes with each step. But if the gun is weaker than the brass, work ups have less useful meaning. One must avoid failure in a weak gun through large inaccurate folklore [published data]. CZ52s are weaker than the brass. Tokarevs are stronger than the brass. My single example C96 tests are inconclusive due to primer piercing due to firing pin to firing pin hole fit.Any ideas on what signs to look for?
What does it all mean?
Don't work up a CZ52 looking for pressure sign on the brass.
Just use conservative published data.
