I had some 30+ ones I called Hogdon about before I tossed them, they said they have one of each can they ever made in the museum.
- I still got a bunch of 30+ year old primers I don't know what to do with.
Seven years ago I got a case of Remington 9 1/2 primers marked 1956 on the box. They were packaged from Remington in a white cardboard box and the primers were packaged in little wooden boxes with cardboard sliders. I reloaded every one of those primers and they all went off and accuracy wasn't a problem.
