Never Tumble Lead Or Exposed Lead Bullets In Walnut Shell!

    It will ruin the media. A friend gave me six boxes of NOS Speer 125 Gr. JSP 9mm bullets and most had a coating of lead oxide on them due to the age (1978) so I dumped all of them in my tumbler for an overnight run and while that did an OK job of removing most of the oxidation it turned the walnut shell gray and will no longer clean brass. Live and learn.

    Thanks for the warning. I regularly tumble pulled 150 gr FMJ to remove the shellac in a Harbor Freight rock tumbler using corn cob media. The base of the bullet is exposed lead but no problems with the corn cob. Guess I won't try it with walnut when the corn cob wears out.
