I picked up a 25lb bag of crushed walnut from Petsmart today. How long do you all reuse your crushed corncob or crushed walnut media? How many shells can you clean on a single bowlful of tumbling media? Right now I have about 500 shells of .50 cal that I want to tumble (vibrate). I have a Lyman tumbler/vibrator and I have been using the Lyman corncob media that I bought with it.

Kindest Regards,
