I guess it will depend on whether it's "Bio" or not, and how it's been stored (out of sunlight? steady temp? low humidity / well sealed container?)
I've got some very very old TM non-Bio ammo knocking around that I might use, if others think it'll be ok.
There's been a bit of discussion on the forum whether Bio ammo does what we expect of it. It seems some will split in sunlight, others need soil bacteria to break them down. They might not break down very well, but then this question is more about how well they'd keep to tolerances.
Intuitively I'd expect Bio's to more easily go out of tolerance.
Are you running tight-bore barrel(s)? If you're not, you've obviously got a bit more leeway with cheap / old ammo too.
