Thank you for that link 243winxb.
Going to the SAAMI site helped me lose what little respect for them that I had still remaining...and no, that's not a joke.
If you found them stating ammo shelf life was 10 years, I bow my head to your search skills, being much better than mine. I waded though dozens of pages, finding nothing relevant to the shelf life question, before giving up, disgusted.
For me, it was like "the answer you seek is on the second from the bottom branch of a maple tree. Here's a roadmap, showing how to get to the
forest..."
Wandering lost in those woods was, however, an enlightening experience....
I have no doubt that a shelf life/storage life of 10 years is something that SAAMI would recommend.
In my opinion, SAAMI seems to be about 2 things first and foremost. #1 safety, and #2 what is best for SAAMI and its members. And, I am not certain about which order those two are placed in....
I believe SAAMI would recommend a shelf life of 90 days, IF they thought they could get the public to accept it...
