I was going through my reloading supplies cabinet today, and found some Rem. 7 1/2 primers that I bought at a store that has been closed for years. These primers have to be 30 yrs. old. The boxes look like new, and the primers themselves show no sign of discoloration or decomposition.
Do you think they are still good? I've got 300 of them, and would hate to waste them if they're OK. I guess I could prime up a couple of casings and see if they still fire, but I thought I'd ask for some opinions too..........
