Tumbled some cases I fired yesterday. The media was nothing but my same old walnut and as usual cut up fabric softener inchlings. Did it outside with the cover off as always. The temperature got to 104 F and the humidity was terrible. After about 4 hours I stared to unload the tumbler.To my surprise all the cases were caked solid with walnut. So much so that it was difficult even to gouge the stuff out wit a 3/16 screw driver blade.
OK! any like experience or brilliant opinions? roger

yeh, had a problem like that. i used too much brass cleaner and ended up with a small drill bit and a couple hours later.wont do that again

Wood swells when hot & wet?

had that happen before more than once. so i quit using walnut and went to corncobs

It's a little cooler this morn . Put the cases in the tumbler without the walnut and turned her loose.Problem solved. roger
