Hello, all.....
I recently obtained a box of 16 rounds of WWII-era ammunition, to display with my Luger (thanks, Russ....

)
These are lacquered steel cases with iron core bullets.
Is there a point at which ammunition of this type becomes unstable or is simply a danger to someone, due to it's age?
These rounds look as though they were made yesterday, and have no outward signs of deterioration, but I thought that I would err on the side of caution, and check with the experts here.
Here are some photos of the ammo in question.
Thanks,
Bob.
