The Before & After
After annealing my cases I like to polish them up in the Lyman 1200 Tumbler with a corn cob media. Having shiny cases is not only aesthetically pleasing but it can also allow you to easily run your eye over each case to inspect it for signs of splitting.
To ensure the corn cob media is primed I use Lyman’s Turbo Charger Reactivator. This Reactivator must be shaken before use and poured into the corn cob media and left to tumble (Do Not Add Your Brass At This Point) for approximately 30 minutes to allow it to work itself into the media and dry off. The drying prevents the media from sticking to your cases and tarnishing them when they are tumbled.
To demonstrate the effects of cleaning your brass with a tumbler and corn cob media, I have included below a before and after photo of my 6.5×55 brass.
