Better then first expectations

run at about 2hours 30mins first batch of thew new 20/40 corncob media with Dillon case polish, good results but odd finding, i guess i just haven't changed my media in a long time but seems like the case polish was trying to evaporate so whatever could got stuck to the roof of the tumbler

no before pic but they were still pretty ugly after sonic cleaning, now they are nice and shiny
