just found some use for it today.i was useing my tumbler for 9mm so i couldnt take the lube off when i done my 30/30 brass so i come up with a brain wave and put the 30/30 brass in a dish and poured the old media over it in less than 5 mins i had all the lube off by moving the brass around by hand and then i could prime the cases has anyone tried this or did you use your tumbler to get rid of the lube ??? from now on thats how im going to get the lube off easy . give it a try it really woks well >>>>thanks oilman :thumbup::thumbup::thumbup:
