I suspect part of the difference in case life is neck
annealing and work hardening of the entire case. RG
ammunition always shows a very marked amount of heat
treating at the shoulder.
Another point with Berdan primed cases is that the case
forming (stamping) and primer pocket/primer hole(s)
formation is done very differently. I was led to believe
that such a system led to thicker case walls at the base
of the cartridge and a thicker casehead.
