I hate to confess but i have shot very old Peters 16 shells on quail with prefect results, Killed 6 for 6, they came out of my grandfather's basement and using them made me feel like I was hunting with him, something I never got to do in person.
Same for some 300 savage ammo.
I have shot WWII and Korean war ammo on the small arms range back in the 1980's with no issue. And motar ammo from 1945 with many issues (almost killed me when it fell near our OP)
All said if the ammo was stored and not water damaged etc it is more than likely safe. Use some judgment and err toward the safe side.
