Thread: Help with Tumbling

Hi guys

I've just been tumbling some of my once fired cases. They've been going 2 hours and they still look like this. Usually an hour and they are good to go. Only difference I can think of is this is a new load with W760 instead of my usual AR2209. Could W760 be harder to clean? It's walnut shell media, not too old I wouldn't think, seems pretty clean still. I have no other additives in there. Never seemed to need them. Any help greatly appreciated.
