For sure, but what would that fact have to do with the observation that the thin, malleable primer cup metal becomes brittle?
The "metal" in the pistol is of different composition, shape , and thickness; and would be unrelated to primer failure- or am I missing something?

Don,
Yes, we are missing quite a few facts here.
You are "assuming" that Lapua Berdan Primers, from that period, were brittle when cold. Were they? A call to Lapua may solve this for us.
Also, the poor quality, hopelessly out of specification, 7.65 ammo you cite above, was not even made then. Relevancy?
Please further enlighten us with your research and readily verifiable facts.
Respectfully,
Sieger
