johngault I to got tired of all the mess from using dry media so I went with the Frankfort Arsenal steel media wet method and have been very happy with it.
I hand de-prime while watching the news then tumble for a couple hours using lemishine & dawn, the water is nasty black when it comes out but that just gets dumped out back.
I dry them in the garage on a wire mesh panel under the ceiling fan overnight.
The primer pockets are completely clean and the brass is nice and shiny.
