    I just bought a new Lyman tumbler and was getting ready to use it when the confusion started. The manual says cases should be tumbled twice.
    Quoting the Lyman manual;
    " The first time is after firing but before resizing. The second time is after resizing but before firing the completed reload."

    Questions
    1). Which media do you use at each step? Walnut, corncob, treated, untreated?

    2). Cleaning the second time, Does that mean tumbling a loaded live round?

    Are you sure it wasn't made in China? Sounds pretty silly to me. Tumble once, load, shoot.

    I never tumble my cases before reloading, simply because I don't want to wipe all the cases with a cloth. The cases will have a residue from the media and will evently score your dies. I do however, clean the necks with a brass brush to remove the powder residue before sizeing.
    The corn-cob media is the best choice, walnut has a oil content to it. Treated will really bring the shine out. But one should wipe the casing after tumbling also, reason being, if you are shooting a high presure load and the cases are real slick the cases could have a chance to seperate in the chamber. This is why I don't use treated media, just my experience.

    Tumble in walnut first for getting really cruddy cases clean. If you want them to really shine, do 'em again in corn cob.

    When they call for tumbling to cleam and after sizing, they are probably refering to Rifle cases. You clean them then use a lube to the case before sizing, you then have to remove the lube after sizing. Two tumblings.

    On handgun cases I always clean with corncob then size and load. Corncob does not leave a residue that will damage the dies by scoring, especially carbide. Walnut can.

    The second admendment GUARANTEES the other nine and the Constitution!

    DO NOT tumble loaded rounds. The tumbling can wear off the powder coating that partially controls the burning rate. This can result in a serious high pressure situation. I normally tumble after sizing/depriming to get the case clean in and out and remove all the resizing lube.

    I tumble twice as it seems to me that powder residue could be worse for dies than a bit of media residue for the tumbler. If I don't tumble twice, I boil the cases in water and scrub them with a bottle brush, inside and out before reloading.
