I inadvertently tumbled some primed brass.  The media is a mix of ~90% crushed walnut (bird litter) and ~10% Lyman corncob green.   Will the primers be ruined by doing this or will they still be good to shoot?

How many cases did you tumble ? safest bet deprime and move on, at 3.99 a hundred your not losing much and avoid the possibility of harming something such as your gun or self. Iv seen a lot of primer tests over the years , and they still work properly , I just always assume the worst I guess

The primers will be okay.  Blow the cases out with compressed air to get all the Lyman trash out.

I would inspect for media in the flash holes and deprime those cases.  That condition is acceptable to some reloaders, but it's not for my needs.

Be careful removing live primers.  It would be very bad if one were to go off. Other than tap the mouths on the reloading bench to clear the flash hole I wouldn't worry about it.  I'd load a handful (10 or so) and ensure that there's no problem and then go from there.

Deprime by a slow steady pull on the press handle when necessary.  If it makes you nervous, put a heavy towel over the press.

Some of us have deprimed more brass than we want to talk about.  I've never had a primer ignite.  Slamming the decapping pin into the primer anvil might cause it to fire, however.

This should not affect the primers themselves but some media could get stuck in the case.  If there is something in the case your powder charge will over flow out of the case.  You can always look inside each case with a flash light

If it were me, I would deprime and use fresh primers.



Removing live primers is a non issue. Slow speed on the press handle and the primers will pop out without indecent.



Wear eye and ear protection.

What is the reason he would need to de-prime?  He could look inside to see if there is any media.

No need.  Knock or blow the media, dust, and residue out and move on.

I was saying what I would do. But I'm picky and have a good supply of primers.
