How long can you keep a magazine loaded without damaging it.

Springer's posted article was a good one....but if it is true, then why is it common to dry fire guns in order to release spring compression in firing mechanisms?

If it's stored properly, it'll be good to go long after you've shed this mortal coil.

I'm still working on some sardine cans of 1950'ish Carbine ammo.

Oh! And 1968 National Match .45 ACP.

It's every bit as good as the day they loaded it!

If ammo went bad in 10 years, I'd be almost out of business in some older guns.

Still shooting some .22 WRF that is at least 60+ years old in one of my 1890 Winchesters. It's way better ammo then the new stuff they load now.

The springs in my original (non drop free)Glock 19 magazines where left fully oaded between range sessions for 13 years before they needed to be replaced. They didn't fail to feed ammo but started intermittently failing to engage the slide stop fully. To get them running correctly I replaced the springs with new springs from Wolf and replaced the followers with an updated style. I'll let you know in the next 7 years or so if 13 years is a good approximation of spring life or not.
