    ...well for me at least anyway, one that I have never gotten a really strong answer on...

    How long can a 30 round mag stay loaded and still be expected to function reliably?

    Indefinately. Its compressing and decompressing that wears on a spring.

    What he said.

    I've used loaded mags from my old unit's war reserve stores that had been loaded for 10 years.

    A long long long time. About 4 years ago my father gave me some 20 round mags that he found which he had loaded sometime in the early 80's. They were stored nicely so the ammo looked good. They shot great. I also fired some rounds from HK33 mags that were stored in an arsenal for about 12 years.

    These types of stories are extremely common.

    Now has your question been answered? Spread the word! Load them up store them and forget about it! The conditions in which they are store is more important- just like ammo.:supergrin:
    Wet -humid hot environment not good for either ammo or Mags!:faint:

    I have some Army Surplus 20 and 30 round mags that have been loaded since somewhere around 1974 I started using one of the 20 rouders for range work about two months ago. I’ve put about 500 rounds through it. Flawless!

    Repeated loading and unloading(using) is what wears out magazines, not storing them loaded.

    I disagree. Indefinitely is a long time, and no one has ever lived that long to test it out.:tongueout:
     
  10. I remember reading once a MP40 and several loaded mags from WW2 were found in a building that was being tore down in Belgium several years ago. They tested the mags by shooting them and they all worked.

    1939 to now = 72 years. Nope not "indefinite". Where's your sense of humour, man?:supergrin:
