Case prep

[White Smoke]

I use a Frankford Arsenal vibrator tumbler with ground walnut shells. Go to a pet store and get lizard bedding. Same thing as sold in the gun stores...ground walnut shells, but MUCH cheaper. I normally use a brass catcher, so my brass is clean when I run it through the sizing/decapping die. Otherwise, I run the cases through the tumbler first to remove any dirt, etc. that can scratch the dies and then do the sizing/decapping. Once sized and de-capped, they go into, or back into, the tumbler for a three-hour run to clean the cases before trimming, chamfering and priming. When you clean the primer pocket, make sure that no media is caught in the flash hole.
