I would load them and just segregate them from any known to be good. If they don't go bang what are you out? Just the time to dismantle them.
I would expect them to be fine. If I found loaded ammo with a slightly tarnished primer I'd shoot it.
Load them..I had a 4 pack of AA's that I left in the back of my pickup and I forgot about them and they got rained on a lot.I put them in the garage and they sat there a couple years ,the primers had rust and corrosion on them and they all went off fine.Jerry
EXTREMELY dangerous! Do not shoot them.
You are lucky that I saw this post. I happened to be a licensed and authorized primer disposal outlet.
Just send them to me and I’ll see that they are disposed of properly.
I had some that sat in the basement for years; when discovered they looked those in the photo. I was trying to figure out how to dispose of them safely...lots of opinions, but not for sure, so I took them to my club and asked a guy I shot with if he wanted them...he used them, no problem.
