I added a quarter bottle of this to my tumbler yesterday and as instructions left it running to disperse and dry.

This morning I added 100 .223 brass and left it running for a few hrs.
When I came to remove the brass I found that the media was stuck together inside the cases and primer pockets.
I have spent the last two hours getting all of it out.The brass has a coating which will need cleaning off.

Moral of story is to just replace the media.

Which media is best as I have used all of the stuff that came with Tunbler. Lyman 1200.
