Speaking of tumbling, does anyone have a source of suitably-sized cobcob? I bought some in the pet store and while it works OK, I have a lot of trouble with it getting jammed up in bottleneck cases (and primer pockets if I deprime first.) I tried vibrating some media through a 1/8"" wire mesh and it is much better, but only about 25-30% of it was below 1/8". The rest I can use in straight-wall cases, of course. Places like Kramer Industries (kramerindustriesonline.com) list corncob amd walnut media in various grits (8/12 would be about right, I think) but they have a 50 lb. minimum- + shipping from the US east coast!
