This time, it's a can of ~200 .38 casings. Yay. I'm guessing these are probably ~30 years old.
I dumped the whole tub into my tumbler and let them clean up for about 3 hours. I started sifting them and discovered...holy cow! These have unused primers!
So any obvious concern is walnut grounds in my flash holes. Given that I am meticulous about making sure these don't look blocked (pen light and paperclip, anyone?), are there any other issues to look out for?
I'm guessing since primers last forever that I'm okay using these. It just makes me sick to think of punching them out if they're perfectly good.
Logic tells me, I could make a dozen minimum loads in them just to see what happens, but I thought I'd pick the brains of the more knowledgeable community before I took matters into my own hands.
Any thoughts?
Thanks,

Every now and then I find a box I didn't know I had. I prime a few cases and throw them in my revolver(just the case no bullets) and test them. The older primers didn't have the sealants that the new ones have they could have been contaminated.

Put a few of the non-loaded cases in a revolver and see if they fire. As long as they haven't been stored in large temperature and humidity extremes they may still be good.

Even if you somehow got a bit of walnut hull jammed in a flash hole, you shouldn't have a major problem unless you're using compressed loads. The primer should just blow the hull into the powder mix as it burns. Whether the hull burns or not, the total mass of ejecta wouldn't be outrageously high so you probably wouldn't even know it was there. I would pop a few with no powder to see if they light off, then load the rest with light loads and have some fun.

ANd remember if it didn't feel right or you didn't see the bullet hit the backstop or target STOP and check the barrel for the bullet. Take a rod to clear the squib, it can save the day.

I just fired a few off in the basement. Wow! That's a lot of bang and fire for such an innocuous looking little thing. Way louder than I expected. I'm guessing these still work. And I have a new respect for small pistol primers.
