Cleaning media

[Kurt]

Well I put some in the tumbler for an hour to try it and it does what it's intention were.
These cases were not just shot so no powder fouling to clean out but they were pretty dark from being in a can for a couple years but they came out bright inside and out.
Yes Arnie I see that the primer pockets were only shiny over the flash hole but I usually use a mix of ceramic and SST pins to take care of the primer pockets.
